I can't understand about the use of adverb of degree
Adverbs of degree tell us about the intensity or degree of an action, an adjective or another adverb.
Common adverbs of degree:
Almost, nearly, quite, just, too, enough, hardly, scarcely, completely, very, extremely.
Adverbs of degree are usually placed:
- before the adjective or adverb they are modifying:
e.g. The water was extremely cold.
- before the main verb:
e.g. He was just leaving. She has almost finished.
- She doesn't quite know what she'll do after university.
- They are completely exhausted from the trip.
- I am too tired to go out tonight.
- He hardly noticed what she was saying.
Enough, very, too
Enough as an adverb meaning 'to the necessary degree' goes after adjectives and adverbs.
