He studied all day long.

He -> Pronoun

studied -> verb (in past tense)

all -> ??

day -> noun ?

long -> adverb ?

I would like to know the part of speech that all is in this sentence. My train of thought: (all day) is a noun in combination. So all might be an adjective ?

1 Answer 1


In this sentence, all is a predeterminer, which gives more information about the noun in a noun phrase (all day).

See definition A1 given by the Cambridge Dictionary

Every one (of), or the complete amount or number (of), or the whole (of)
- He studied the whole of the day long.
