Comparison (grammar)

Comparison, in grammar, is a property of adjectives and adverbs.

The first degree is positive:

The second degree is comparative:

Bill is kinder than Joe.

The third degree is superlative:

Likewise, the use of more as in more quickly is comparative,
and the use of most as in most quickly is superlative.
