Pronouns & Possessives: I, my, mine

A1 Grammar

1. Simple explanation

A pronoun is a small word that stands in place of a name, so we do not say the name again and again: 'Anna is happy. She is happy.' English pronouns do three different jobs. Subject pronouns (I, you, he, she, it, we, they) do the action of the sentence. Object pronouns (me, you, him, her, it, us, them) receive the action — the action happens TO them. Possessive words show that something belongs to someone: 'my book' means the book belongs to me, and 'The book is mine' means the same thing.

2. Detailed explanation

Start with the very first idea: names. In English we give people names — Anna, Tom, Mr. Lee. If we use the name in every sentence, our English sounds like a robot: 'Anna is my friend. Anna is funny. I like Anna.' Pronouns are the small helper words that replace names: 'Anna is my friend. She is funny. I like her.' A pronoun does the same job as a name, but it is shorter, and English gives each job its own pronoun.

Job 1 — the doer: subject pronouns. A subject pronoun stands at the start of the sentence and does the action: I, you, he (a man or boy), she (a woman or girl), it (a thing or an animal), we (I and other people together), they (other people or things). Word by word: 'She is happy.' She (the person — a woman, the subject, the doer) + is (the verb 'be' in the form for she) + happy (an adjective — a word that describes how she feels). The pronoun must match the person, and the verb changes with it: 'I am', 'she is', 'they are'.

Job 2 — the receiver: object pronouns. When the action lands on a person, the pronoun changes its shape: me, you, him, her, it, us, them. Object pronouns come after verbs (action words like see, call, love, know, help) and after small connecting words like to, with, for and from. Word by word: 'I called him yesterday.' I (subject — the doer) + called (the action) + him (object — the man who received the call) + yesterday (when it happened). Notice: the same man is 'he' at the start of a sentence, but 'him' after a verb: 'He called me' and 'I called him'.

Job 3 — the owner: possessives. Possessive words answer the question 'Whose?' — who does this thing belong to? They come in two sizes. Short forms (my, your, his, her, its, our, their) must always stand right before the thing: 'my phone', 'her bag'. Long forms (mine, yours, his, hers, ours, theirs) stand alone and replace the thing completely. Word by word: 'This bag is hers.' This bag (the thing we are talking about) + is (verb 'be') + hers (the long possessive — it means 'her bag', and the word 'bag' disappears because we already said it). The rule to remember: if a thing-word (bag, car, book) comes after, use the short form; if nothing comes after, use the long form.

One special trap: 'its' and 'it's' sound exactly the same but work differently. 'Its' (no apostrophe — the small mark ') is a short possessive: 'The dog hurt its leg' — the leg belongs to the dog. 'It's' (with an apostrophe) is a short way to write 'it is': 'It's cold today' means 'It is cold today'. Quick test you can always use: if you can say 'it is' in the sentence, write 'it's'; if you cannot, write 'its'.

4. When to use it

• To avoid repeating a name: 'Tom is late. He is always late.'
• To talk about yourself and others in any sentence: 'I live in Ohio. Do you live here?'
• After verbs like see, call, help, love, know: 'I know her.' 'Can you help us?'
• After prepositions (to, with, for, from): 'This gift is for you.' 'Sit next to me.'
• To show ownership before a noun: 'my keys', 'their house', 'its color'
• To show ownership at the end of a sentence, with no noun: 'That jacket is mine.' 'The decision is theirs.'

5. When NOT to use it

• Don't use a subject pronoun after a verb: ✗ 'I saw she' — use the object form: ✓ 'I saw her.'
• Don't put a noun after a possessive pronoun: ✗ 'This is mine book' — say ✓ 'This is my book' or ✓ 'This book is mine.'
• Don't add an apostrophe to possessive pronouns: ✗ 'yours'' / 'her's' — write ✓ 'yours', ✓ 'hers'.
• Don't confuse 'its' (ownership) with 'it's' (= it is): ✗ 'Its raining' — ✓ 'It's raining.'
• Don't say 'me and Sara went' in careful English: ✓ 'Sara and I went.'
