What are the in the use of the comparative and superlative?

Answer 1

Comparatives end in -er (e.g. better, bigger, faster, stronger, taller, etc.) and superlatives end in -est, generally. (e.g. best, biggest, fastest, strongest, tallest, etc.) Comparatives mean something is better, bigger, whatever-er than something else. Superlatives mean something is bigger, better, whatever-er than EVERYTHING else involved. So "Susan is faster than John" is comparative, and "Alex is the fastest of his friends" is a superlative.
