I have been bewildered semantically by the use of the in front of soup in the following sentence.
What happened to the rest of the soup that we ate yesterday?
I have come across this sentence while reading a book called 'A' and 'The' Explained: A Learner's Guide to Definite and Indefinite Articles, written by Seonaid Beckwith.
This is actually an exercise: which is more appropriate to use "the" or no article in the parentheses in the sentence What happened to the rest of () soup that we ate yesterday? The author says the answer is "the."
Perhaps, the sentence means: There was soup. We ate some of it and left the rest over. What happened to the rest of the (whole) soup? I have thought "the soup that we ate yesterday" is now "in our stomachs," so there is no leftover soup regarding "the soup that we ate yesterday."
It's like What happened to the rest of the money that we spent yesterday? Literally, the money has been already spent, and thus there is no money left. When the definite article is used in the expression the rest of the noun, I suppose the noun represents the whole, not some, of it, as the rest generally calls for.
Indeed, the soup that we ate yesterday is apparently some, not all, of the whole soup prepared, and has already been consumed; so I presume the rest of the soup that we ate yesterday no longer exists.
Language is not always completely logical; some wiggle room is left for interpretation; and common sense plays a role in understanding a sentence.
Anyway, do you see any hiccup in the sentence What happened to the rest of the soup that we ate yesterday? as a native speaker?
Could you provide any reasoning or grammatical explanation on the use of the in front of soup?
