Adverb or adjective? Or something else?
This question came up a couple days ago at work, and spurred a lively, if puzzled, debate:
In the following sentence, what is the function of the word “black”?
The barista served the coffee black.
“Black” doesn’t seem to be adjectival, modifying “coffee”, because of the position: there’s a semantic difference between “served the coffee black” and “served the black coffee.” But it hardly seems adverbial, describing the manner in which the serving was done.
The same question applies to “painting the wall blue” and other similar constructions.
It seems to me that the adjectives here act like a kind of double accusative, but I thought double accusatives were typically used with verbs like “make.” So I really don’t know what kind of construction it is; I just know that I use it a lot.
