indefinite

When we are talking about a word, inflection, or phrase, ‘indefinite’ means not determining the person, thing, time, etc. referred to.
An indefinite time might be expressed with present perfect. “I have done it” Nobody knows exactly when.
An article can express something that is not defined. “Give me a chair” Which chair doesn’t matter, anyone is ok.
Indefinite pronouns also carry the same vague meaning: “Somebody took my chair” I don’t know who…etc.

degree adverb + indefinite pronoun ‘ABSOLUTELY NOTHING’

It is very hard to distinguish between levels for some items because it is not clear on the EGP too.
