degree

This refers to the different levels of comparison made by adjectives and adverbs. There are three degrees, positive, comparative, and superlative.  For example:

The good dog.        (positive; no comparison implied)

The better dog.      (comparative; comparison between two implied)

The best dog.         (superlative; comparison between three or more implied)


Adverbs can also have degree:

She ran fast.

She ran faster.

She ran fastest.
