At A2 level, you need to compare two or more things using short adjectives. This lesson covers three key structures: -er (comparing two), -est (comparing three or more), and as...as (showing equality). We’ll explain the rules clearly with plenty of examples.
Use -er when comparing two people or things.
Structure: [Noun] + is + [adjective-er] + than + [noun]
✅ My brother is taller than me.
✅ This phone is cheaper than that one.
Use -est when describing the most or least in a group of three or more.
Structure: [Noun] + is + the + [adjective-est]
✅ She is the tallest in her class.
✅ This is the happiest day of my life.
Use as [adjective] as to say two things are the same in some way.
Structure: [Noun] + is as + [adjective] + as + [noun]
✅ My book is as interesting as yours.
✅ He is as tall as his brother.
⚠️ Never use -er or -est in "as...as" sentences.
Some common adjectives do not follow the -er/-est rule. Memorize these:
| Positive | Comparative | Superlative |
| good | better | best |
| bad | worse | worst |
| far | farther / further | farthest / furthest |
✅ She is a better cook than me.
✅ This is the worst movie I’ve seen.
✅ Tokyo is farther than Osaka.
correct “This pizza is as tasty as the one we had yesterday.”
incorrect “This pizza is as tastier as...” — never use -er in "as...as"
