Comparative and superlative adjectives grammar worksheet for teens, designed by the British Council.

Here are the answers to the exercises on comparative and superlative adjectives.

1. Check your grammar: true or false

1. True (We usually add *-er* for short adjectives, like *fast* → *faster*).
2. True (We usually add *-est* for the superlative, like *fast* → *fastest*).
3. False (We often change spelling! For example, *big* becomes *bigger*, and *happy* becomes *happier*).
4. True (We use *than* to compare two things, e.g., "taller *than* you").
5. True (We almost always put *the* before a superlative, e.g., "*the* best").
6. True (Long words use *more* or *most*, e.g., *more beautiful*).
7. False (There are only a few common irregular ones, like *good/better/best* and *bad/worse/worst*).

2. Check your grammar: gap fill writing

1. The clothes here are better than in my town.
*(Irregular: good → better)*
2. That’s my worst mark ever!
*(Irregular: bad → worst)*
3. It’s farther (or further) than I thought – I think we’re lost.
*(Regular: far → farther/further)*
4. That’s the most disgusting meal I’ve ever had!
