1.INTRODUCTION

This book aims to bridge the gap between the study of Modern English grammar and its practical use in real-life situations. Designed with both self-learners and classroom environments in mind, it combines clear explanations with carefully structured exercises, ensuring that learners can immediately apply what they study. The language is intentionally simple, avoiding unnecessary jargon, while maintaining a tone that is both elegant and precise. Each unit is written to encourage active engagement, making the learning process dynamic rather than mechanical.

The structure of the book follows a logical progression where each unit builds upon the knowledge introduced in the previous ones. However, it has also been designed to allow flexibility: students who have difficulties only in specific areas can pick up any unit independently without feeling lost. In a classroom setting, a teacher can typically complete one unit in about an hour, while learners studying on their own can work through each unit in shorter, focused sections of around ten minutes each. This modular approach ensures that progress is steady yet adaptable to different schedules and learning speeds.

A distinctive feature of this book is its integration of explanations and exercises. Each new concept is followed by practical activities that reinforce understanding, allowing learners to practise immediately rather than passively memorising rules. The exercises are varied—ranging from simple sentence-building tasks to short writing challenges—encouraging creativity while consolidating grammatical accuracy. This combination of clarity, practice, and creativity makes the method dynamic and accessible.

The book also addresses the diversity of Modern English as it is spoken across the world. While focusing on the grammatical foundations common to all varieties, it provides examples and notes on differences among accents and usage patterns from British Received Pronunciation (RP), Standard American English, Irish English, and Australian English. This comparative approach helps learners not only understand grammar but also appreciate the cultural and phonetic richness of the language.

In terms of content, the material covered corresponds primarily to the A1 and A2 levels of the Common European Framework of Reference for Languages (CEFR). However, certain topics are expanded slightly beyond these levels, incorporating useful insights from early B1 structures. This ensures that learners are well-prepared to progress naturally to intermediate stages, without abrupt transitions.

By the end of this book, a student will be able to:

Apply grammar rules to short texts and conversations with accuracy and fluency.

Understand and use essential grammatical structures of Modern English.

Form clear and correct sentences in both spoken and written contexts.

Recognise and adapt to variations in English across different accents and cultural settings.

Handle basic everyday communication with confidence, including describing events, expressing opinions, and asking questions.

2. PRONUNCIATION – VOWELS

English employs one single writing system, unlike other languages such as Chinese, Japanese, Serbian, and others, which make use of more than one writing system. Such a writing system is the Roman alphabet, the same used for Spanish, French, German, Latin, and so on. However, the correspondence between symbols and the real sounds of English is not always intuitive and easy to grasp. In fact, English has more sounds than the alphabet has letters.
That is one of the reasons why you come across symbols surrounded by ‘/’ after an English word in a dictionary. Such symbols represent one single sound and never deviate from that sound. Thus, the symbol /i/ stands for a certain sound even when English uses other letters rather than ‘i’ to represent it. For example, you may look at the word ‘seed’ and not realize right away that the letters ‘ee’ have the sound represented by /i/, but the use of this symbol beside the word in a dictionary will help you understand that the word is pronounced with /i/ even though it is spelled with other letters. Take a look at the following dictionary entry for the word ‘seed:’

SEED /siːd/ 1. An ovule produced by a plant, which contains a new plant.

The two main pronunciations of English are called General American and Received Pronunciation, the standard accents of the United States and the United Kingdom, respectively. This book will exhibit both pronunciations, being up to you and your teacher to pick up either or both during your learning process. The abbreviation ‘US’ is used for when the General American pronunciation is given, and the abbreviation ‘UK’ is used for when the Received Pronunciation is given.

Below is a list of core vowel letters used in English. Click on each one to hear its pronunciation and begin familiarizing yourself with the sound system. Note that the order below does not reflect the sequence in which these vowels appear in the alphabet, but rather displays vowels in groups according to how similar they are. Consonants and diphthongs are addressed in the next chapter, and the alphabetical symbols are discussed two chapters later. It is in that chapter that we will finally examine the full order of symbols. The vowels in blue are used only in Received Pronunciation, and the vowels in red are used only in General American. This way you can follow just one accent if you will. If you look for a different accent of English, resort to the volumes on pronunciation.

/i/ (this sound is represented by i, y, ee, or ea as in machine, study, seed, and lead)
/ɪ/ (this sound is represented by i, e, or y as in sit, deepen, and analysis)

Your turn: Click on the following words to hear their sounds and determine if you hear /i/ or /ɪ/. Ask your teacher if you should go through all of them or a selection of words.

4. WRITING SYSTEM

Teach how to spell and then teach English like a syllabary.

5. BE, DO, HAVE

Even though you are here to learn English, it must be said that you already know a bit of this language. In fact, languages are not random chunks of words and sentences but rather show familiarity to one another. That happens in two ways:

1. Two languages have influenced each other throughout the centuries. Examples: French and English, Chinese and Japanese, Sumerian and Akkadian, Arabic and Spanish, Hindi and Bengali, etc.
2. Two languages descend from an older common language. Examples: Italian and Romanian, Portuguese and Spanish, Russian and Ukrainian, Amharic and Tigrinyan, Hebrew and Aramaic, etc.

So chances are that you already know a good deal of English from words in your native language. Besides, your native language probably shares some grammatical features with English, enabling you to identify certain patterns on the spot. Here are some examples:

1. Languages tend to place their adjectives before or after the noun, i.e., you either say red apple or apple red. Fortunately, English uses both word orders. So you are already familiar with some of the combinations that we shall see.
2. Languages either have verb tenses (past, present, future), aspects (perfective or imperfective) or both. English has both, so you carry something from your native language that resembles these features.

English has three fundamental words that are used in the construction of the language: be, do, have. Moreover, the word for the person who speaks is ‘I,’ the word for the listener or listeners is ‘you,’ and the word for more than one speaker is ‘we.’ These three, alongside the other three (be, do, and have) are the building blocks of the language.
Maybe in your native language you have a word for a singular ‘you’, and another for a plural ‘you.’ English used to behave like that, but nowadays it exhibits only a very general and somewhat vague ‘you.’
You can just link the ‘do,’ ‘be,’ and ‘have’ to ‘I,’ ‘you,’ and ‘we.’ Thus, you can say: I do, you do, we do, I have, you have, we have, etc. It’s only ‘be’ that behaves a bit different; you attach ‘are’ to ‘you’ and ‘we,’ but you attach ‘am’ to ‘I.’ You use ‘be’ when you refer to the name of the verb. So, we are left with:

DoHaveBe
I doI haveI am
You doYou haveYou are
We doWe haveWe are



Be links the speaker to features of that same speaker (age, occupation, nationality, affiliation to a group, role, feelings, quality, etc), do links the speaker to things brought into existence by him (do homework, do exercise, do an experiment, do a course, do research, do the shopping, do your hair, do the dishes, do harm, do your best, etc). Have links the speaker to things attached to the speaker (possessions, money, clothes, a disease, skills, etc).

Your turn: What is the difference between ‘I do the course’ and ‘I have a course?’ Think for an instant and check the answer

Answer

‘I do the course’ means that I attend classes, take lessons, answer questions, study, etc.
‘I have a course’ means that I am a student who finished the course or a teacher that created the lessons.

Your turn: If you have finished a course, do you have or do you do a course?

Answer

You have a course. So you say: ‘I have a course.’

Your turn: if a friend of yours wants to learn English and you know of a course that might be what your friend needs, do you say that you do or that you have a course?

Answer

You tell your friend: ‘I have a course’ (I have a course that is just what you need). You are not the teacher and you haven’t necessarily finished that same course, but you are in a relation with the course mentioned.

Your turn: Now, if you are a teacher, do you do or do you have a course?

Answer

You have a course. So you say: ‘I have a course.’

Your turn: if you work at a company and start taking classes at a nearby language school to earn a better position, do you do or do you have a course?

Answer

You do a course. So you say: ‘I do a course.’

Your turn: if the company itself offers you the course that you need, does the company do or have a course?

Answer

The company has the course. So the company says: ‘We have a course’ (‘we have a course on that subject that you need)

Your turn: if you are a student and you notice that an exam is scheduled for tonight, do you have or do you do an exam?

Answer

You have an exam. So you can say: ‘I have an exam tonight.’

Your turn: if the night comes, you go to school, and you start your exams, should you say that now you have or that now you do an exam?

Answer:

For as long as you are writing on paper, typing on a computer (if your exam is online) or doing any other activity related to the exam, you can say that now you do an exam. So you should say: ‘I do an exam.’

Your turn: if you and your friend are in doubt about a certain subject and you look it up on the internet, do you do or do you have a web search?

Answer

You do a web search. So you can say: ‘We do a web search’

Your turn: if you want to find the link to a website you visited a few days ago, do you say that you do a web search in your browser history or that you have a web search in your browser history?

Answer

You say that you have a web search in your browser history. So you can say: ‘I have a web search in my browser history’

Your turn: if there is a lecture saved on your phone as an audio file for you to listen to it later, do you do or do you have a lecture on your phone?

Answer

You definitely have a lecture on your phone. Otherwise, you would be the lecturer. So you can say: ‘I have a lecture.’

Your turn: Would you say that you are 20 (years) or that you have twenty years?

Answer

It is common for many languages to make use of ‘have’ for someone’s age, but that goes against the logic of English. French, Spanish, Portuguese, Italian, and many others use ‘have’, but think like a native English speaker. You are 20 years because you are living the 20th year of your life right now; it is your current state. In this situation, you should say: ‘I am 20.’ A case of having years will be shown next.

Your turn: if that same company asks you how long you have worked in that position, do you say that you are 5 years of experience or that you have 5 years of experience?

Answer

You most certainly say that you have 5 years of experience. Those five years are like your luggage, you are in a relation with something that was done in the past and now is just the background from which you move forward. So you say: ‘I have 5 years of experience.’

Your turn: now, if you look back at your ten years in the army, should you say that you did or that you had five years in the army?

Answer

You did five years in the army. So you can say: ‘I did ten years in the army.’ We haven’t seen the past form of ‘do’ (‘did’) and we won’t see it for some time, so don’t worry about it.

Your turn: One more time, do you have or do you do a course on Mathematics if you have already finished it? How do you tell someone that they have finished it without using the word ‘finish?’

Answer

You have it, and so does your friend. So you say ‘I have a course’ and ‘you have a course’ (on Mathematics);.

Your turn: Do you say that you are Mexican or that you have Mexican? Think about it.

Answer

When it comes to nationalities, you are of this or that nationality. So you should say: ‘I am Mexican.’

Your turn: Now you want to state the nationality of a friend. Do you say ‘you are Argentinian’ or ‘you have Argentinian?’ Use the right form of the verb.

Answer

‘You are Argentinian.’

Your turn: Now think not of your nationality, but rather of your country. Supposing that you are from Egypt and you love your country very much, do you say that you have Egypt in your heart or that you are Egypt in your heart?

Answer

You have Egypt in your heart. So say: ‘I have Egypt in my heart.’

Your turn: Now, do you say that you have Korea on your list of next destinations or that you are Korea on your list of next destinations?

Answer

You say: ‘I have Korea on my list of next destinations’

Your turn: If you are at the gym lifting weights, do you do exercises or do you have exercises?

Answer

You do exercises. So you should say: ‘I do exercises.’

Your turn: Now someone questions you about a certain exercise that they think is missing on your list of exercises. Do you say that you have that exercise on your list or that you do that exercise on your list?

Answer

You answer right away that you have that exercise on your list. But you might as well say that you don’t have it but you like it so much that you do it. Or maybe you want to emphasise that you have it and do it, so you can say both ‘I have that exercise’ and ‘I do that exercise.’

Your turn: if someone does you wrong, do you say that you are angry or that you have anger?

Answer

You say: ‘I am angry.’ (‘am’ is the right form of the verb)

Your turn: if you are talking to a friend and you vent about a feeling that has lived in your heart for some time but that you want to get rid of, how do you think you would express that? Do you say ‘I am angry’ or ‘I have anger?’

Answer

You say something like: ‘I have anger burning inside me — help me get rid of it.’ This sentence might also be said to a therapist. If you pay close attention, you will notice that that person is not living the anger, they stand at a distance from it, loathes it, and, therefore, is at most in a relation with it.

Your turn: Can you think of two different situations, one in which you would say ‘I am a doctor’ and one in which you would say ‘I have a doctor?’

Answer

If you say ‘I am a doctor’ (‘am’ is the right form of ‘be’ here) that means that you are stating your profession. If you say ‘I have a doctor,’ you are probably saying that you go to a doctor who you trust and who has treated you for years so that now you can recommend that doctor.

Your turn: if you are not bald, do you say that you have hair or that you do hair?

Answer

You say: ‘I have hair.’

Your turn: what would you say when you change your hair and make it look a certain way? ‘I have hair’ or ‘I do my hair?’

Answer

You say: ‘I do my hair.’ The word ‘my’ is added to make the sentence look more natural. To do one’s hair is a way in which English expresses any significant modification to someone’s hair.

Your turn: if the sink in your kitchen has a pile of dishes that you have to wash later, do you say that you have or that you do a pile of dishes?

Answer

If you will only wash them later, you can say: ‘I have a pile of dishes for tonight.’

Your turn: What about when you finally face the pile of dishes and start washing, rinsing, soaking, and finally drying it? Do you say that you have or that you do the dishes?

Answer

You say: ‘I do the dishes.’ You may be tempted to use a different verb for this action (wash, rinse, soak, clean), maybe your native language does not have a single verb that describes anything that you do to the dishes to make them clean. But English has the verb ‘to do,’ which fits perfectly here. In reality, you will soon realise how English tends to simplify our patterns of thought.

Your turn: Do you say that you are the shopping or that you do the shopping?

Answer

You should say: ‘I do the shopping.’

Your turn: if you and your friend grab a deck of cards to show others a trick you have learned, do you have or do you do a magic trick?

Answer

You do a magic trick. So you should say: ‘We do a magic trick.’

A number of these cases can also have a different verb. You can say ‘take a course,’ ‘give a lecture,’ etc. But these simple sentences with ‘be,’ ‘do,’ and ‘have’ will often pop up in conversation and texts.

6. DO / O (MOVE, PROVE, LOSE, TO) / EE (SEE, TREE, KEEP, STREET, MEET)

Now that you have seen the three verbs ‘do,’ ‘be,’ and ‘have,’ we should start learning how they come to be so important to English Grammar. Every verb tense in English is built with one of those verbs, and in this chapter we will start our journey with the verb ‘do.’
We are going to add other verbs after ‘do’ to create whole sentences. You will often see the word ‘a’, which means that the objects we are describing are not specific. So, ‘a tree’ is any tree

Your turn: How would you say ‘I lose my key?’ ‘My keys’ is ‘my keys’ (‘my’ is ‘my,’ and ‘key’ is ‘key’) and ‘lose’ is ‘lose.’ The sound produced by the ‘o’ in ‘lose’ is teh same as in ‘do.’

Answer

‘I do lose my key.’

Your turn: How do you say ‘you see a tree?’ ‘See’ is ‘see,’ and ‘tree’ is ‘tree.’ In both cases, the combination ‘ee’ sounds like the ‘e’ in ‘be’. We are going to see many words with ‘ee’ in this chapter.’

Answer

‘you do see a tree’

Your turn: How do you say ‘we see a street?’ ‘Street’ is ‘street’

Answer

‘We do see a street’

Your turn: How would you say ‘I see a tree, and you see a street?’ The word ‘and’ is ‘and.’

Answer

‘I do see a tree, and you do see a street.’ (notice that we separate the two sentences with a comma, that is, with ‘,’)

Your turn: How would you say ‘I meet my friend?’ ‘Meet’ is ‘meet,’ and ‘friend’ is ‘friend.’

Answer

‘I do meet my friend.’

Your turn: How would you say ‘we see a street?’

Answer

‘We do see a street’

Your turn: How do we say again ‘I see a tree, and you see a street?’

Answer

‘I do see a tree, and you do see a street.’

Your turn: How would we say ‘I see a tree, but you see a street?’ The word ‘but’ is ‘but.’

Answer

I do see a tree, but you do see a street

Your turn: How would you say ‘I meet a client?’ ‘Client’ is ‘client.’

Answer

‘I do meet a client.’

Your turn: How would you say ‘we meet a customer?’ ‘Costumer’ is ‘customer.’

Answer

‘We do meet a customer.’

Your turn: How would you say ‘I keep a secret?’ ‘Keep’ is ‘keep,’ and ‘secret’ is ‘secret.’ The ‘ee’ in ‘keep’ again is like the ‘e’ in ‘be.’

Answer

‘I do keep a secret’

Your turn: How would you say ‘I keep my exam?’ Imagine your classmate insists that students always have to submit their exams to the teacher, and that the teacher never returns them — that this has always been the case. In response, you say, ‘I do keep my exam.’

Answer

‘I do keep my exam.’

As you can see, it makes perfect sense that we signal that we are talking about an activity (hence the use of ‘do’) and then we introduce the verb we are dealing with. If we see something, we ‘do see’ it. However, English mostly drops the word ‘do’ and builds the sentences without it. ‘Do’ is implied, and keeping it adds emphasis to the sentence. The last sentence is a good example; you have to emphasise to your classmate that you guys can really keep your exams after they are corrected. From now on, we will bear that difference in mind.

Your turn: How do you say ‘you lose my key’ without emphasis?

Answer

‘you lose my key.’

Your turn: What about the same sentence with emphasis? Suppose that someone denies vehemently that they have lost your keys, despite you knowing that they have lost it. Think of a situation in which you say that someone always loses your key.

Answer

‘You do lose my key’

Your turn: How would you say ‘I meet my client’ without emphasis?

Answer

‘I meet my client.’

Your turn: How would you say ‘I see my teacher’ without emphasis?

Answer

‘I see my teacher.’

Your turn: How would you say ‘we see a doctor? without emphasis’ This expression ‘see a doctor’ is the standard way of saying that you pay a visit to your doctor and state your health condition.

Answer

‘We see a doctor.’

Do not forget the emphasis that you can give to a sentence with the use of ‘do.’ Shortly, we will see the same phenomenon with ‘be’ and ‘have.’

Your turn: How would you say ‘We see a street’ with emphasis?

Answer

‘We do see a street.’

Your turn: How do you say ‘We move to Ireland’ without emphasis? ‘Move’ is ‘move,’ and ‘Ireland’ is ‘Ireland.’ The ‘o’ in ‘move’ is like the ‘o’ in ‘do.’ But when someone moves, they move ‘to’ a place. The word ‘to’ is ‘to.’

Answer

‘We move to Ireland.’

Your turn: How would you say ‘I move to Ireland, and you move to Africa’ without emphasis? ‘Africa’ is ‘Africa.’

Answer

‘I move to Ireland, and you move to Africa.’

Your turn: How would you say ‘I move to Africa, but you move to China’ without emphasis?

Answer

‘I move to Africa, but you move to China.’

Your turn: How would you say ‘I see my phone’ with emphasis? Do not forget that ‘phone’ is ‘phone.’

Answer

‘I do see my phone.’

Your turn: Do you do or have a course if you have been taking classes in that course?

Answer

‘I do a course’

In English, you generally do a course ‘on’ something. And we can start using that construction now.

7. CONNECTING IDEAS

13. PREPOSITIONS

English connects words and expresses ideas of time and space with what we call prepositions. So, when you want to make it clear where something is or when something happens, prepositions are very well suited for that. We are going to see three of them: in, on, and at.
The preposition ‘in‘ indicates that something is contained in a container. The container surrounds the thing contained entirely. We might say, for instance: ‘I am in the living room.’ In fact, supposing you entered a living room, and supposing you don’t have one foot on the floor of the living room and another outside the room, you are contained by a container called living room.



Your turn: Imagine the man has a cat and a box. If all the cat is surrounded by all the air that is surrounded by all that box, can we say that the cat is in the box? Very well, the cat is indeed in the box.

Your turn: Now, let’s try something a bit more problematic. In the first scenario, we have a boy (the child of that man) swimming, and all of his body is surrounded by the water as he has dived quite deep. Can we say that the boy is in the water? We certainly can! But let’s move on to the second scenario: the boy swims, but his head and part of his trunk is not surrounded by the water. Let’s say that he floats peacefully as when someone is unwinding for a bit. Can we say that he is in the water if now part of him is not surrounded by water? Think about it! The answer is that he is still considered to be in the water. Real life is messy. Bodies bend; doors stand open; people lean out of windows. English normally ignores tiny bits that poke through a boundary. As long as the relevant part (the part that counts for the activity or viewpoint) is within the region, speakers are comfortable saying in.


Talking about water, it’s high time we encountered the preposition on. This preposition indicates that something exists and is in contact with other things. Example.: The picture on the wall.



Some people stubbornly maintain that ‘on‘ means the same as on top of, i.e., situated over something but still in contact. Well, that is only partially true – the previous example has a picture on the wall. The picture is in contact with the wall, but by no means must we infer that it is on top of the uppermost brick that belongs to that wall. As a matter of fact, we tend to say something is ‘on’ even when it’s under another thing: ‘The light bulb is on the ceiling.’ In that case, not only the light bulb isn’t on top of the ceiling, but it’s actually under the ceiling (although still touching it).

Your turn: Going back to the boy in the water (who is in the water even though parts of him are out of the water), imagine that he has one of those floating plastic toys next to him (say an action figure). We can assure with a high degree of certainty that the toy is only in contact with the surface of the water rather than submerged in it. In that case, we say: ‘the toy is on the water.’



The next preposition is ‘at.’ We use this preposition when we mean that something is very near, next to, adjacent to another thing. Think of yourself getting ready to have dinner with your family. It would be quite strange to say that you are going to sit in the table, as that would imply that you fit inside the wood of which the table is made. But it would be equally preposterous to say that you are going to sit on the table. ‘On the table’ means that you will use the surface of the table as a seat – maybe you intend to sit on top of the table. But that’s inappropriate for a family dinner, right? That’s a scenario where we are left only with the preposition ‘at’ to help things make sense. You sit ‘at’ the table, i.e., adjacent to the table (next to it).



Your turn: If the man in the living room is waiting for his wife, and she finally arrives, must she knock on, in, or at the door? You probably already know that she shall knock on the door. Take a moment to think about how things match perfectly – we use ‘on’ because her hand is in contact with the surface of the door.

Your turn: We already know that the man is ‘in’ the living room. But what can we say about the woman in relation to the door? Is she… ugh… ‘in’ the door? It can’t be, can it? Is she ‘in,’ ‘on,’ or ‘at‘ the door? Pause and think about the consequences of using this or that preposition. Congratulations if you think she is ‘at‘ the door.
