The correct answer is "We didn't see their photos, but they saw ours.", which uses the subject pronouns "we" and "they" and the possessive adjectives "their" and "ours."
Possessive
- ✅ its tail — ❌ it's tail (it's = it is, not possessive)
- ✅ the students' essays — plural possessive (apostrophe after the s)
- ✅ Sarah's book — singular possessive ('s)
- ✅ a friend of mine — possessive pronoun (not my)
Possessives show ownership: nouns use 's (singular) or s' (plural ending in s). Pronouns have special forms: my/mine, your/yours, his, her/hers, its, our/ours, their/theirs.
Trap: its (possessive) vs it's (= it is). Possessive pronouns NEVER use apostrophes — that's the opposite of nouns.
Pronoun
- ✅ between you and me — ❌ between you and I (objective case after preposition)
- ✅ its colour — ❌ it's colour (it's = it is)
- ✅ She did it herself. — reflexive pronoun
- ✅ The person who called… — relative pronoun
Pronouns replace nouns: personal (I/me/my), demonstrative (this/that), relative (who/which/that), interrogative (who?/what?), reflexive (myself), indefinite (everyone/nobody). They carry case that nouns have lost.
Trap: pronouns are where English case still matters: I vs me, who vs whom, its vs it's. Get these wrong and it's instantly noticeable.
A1 | Elementary | Beginners
- ✅ My name is Anna. — present simple of be
- ✅ Where is the station? — basic *wh-*question
- ✅ I have two brothers. — possession with have
- ✅ She likes coffee. — third-person -s
These are A1 sentences — the starting level of the CEFR framework. At A1 you can introduce yourself, ask and answer simple personal questions, and handle basic everyday transactions using present tense, be/have/do, and core vocabulary.
If you can say these but freeze at normal speaking speed, you're solidly A1 — and that's exactly where to start.
Easy
- She is a teacher. — one verb form, one rule
- I have two cats. — basic possession, short sentence
- He doesn't like coffee. — simple negation with do-support
- Only one answer is clearly correct; distractors are obviously wrong.
Easy marks beginner-level challenges: A1–early A2, one rule at a time, everyday vocabulary, no trick questions.
Use "Easy" when you want to build confidence on a specific rule without interference from other grammar or tricky contexts.
