What is the difference between comparative and superlative adjectives?

A comparative adjective compares exactly two things, such as bigger. A superlative adjective compares one thing with a whole group of three or more, such as the biggest. Comparatives usually pair with than, while superlatives always need the before them and never take than.

Does this comparative adjectives test have answers?

Yes. All 50 questions in the five exercises show the right answer and a short, simple explanation when you check them. Nothing is hidden, the test is completely free, and you do not need to make an account before you start practising today.

When do I use more instead of -er?

Use more with longer adjectives, usually two syllables or more, such as more beautiful or more expensive. Short adjectives like tall or big simply add -er instead, as in taller and bigger. Never use both markers together, so more bigger is always wrong.

When do I use than after an adjective?

Use than when you compare two things and name the second one.

Why is more better wrong?

Better is already the comparative of good, so more adds nothing.
