How can an adjective follow and modify an adverb in “somewhere new”? Is this ellipsis?
- I would like to go somewhere new tonight.
- I met someone nice at the party
Are the preceding two sentences the same as the following, but with ellipsis applied?
- I would like to go somewhere [that is] new tonight.
- I met someone [who is] nice at the party.
If not, how can this apparent ᴀᴅᴠᴇʀʙ + ᴀᴅᴊᴇᴄᴛɪᴠᴇ construct be otherwise explained?
After further research, I think that somewhere is actually an indefinite pronoun in this sentence, although it only appears as an adverb in the Cambridge Dictionary.
Both of my examples are therefore INDEFINITE PRONOUN + ADJECTIVE which, according to this article, requires a postpositive adjective.
The remaining part of the puzzle is why somewhere new can follow go without a to- preposition. tchrist in his comment on my question describes somewhere new as a locative adverbial, which would not require a to- preposition.
