countable nouns and uncoutable nouns: water and an (the) apple(s) [duplicate]
Solution 1:
It's not that complicated in the abstract.
- Uncountable nouns are treated as singular ("some flour goes into the pie").
- Countable nouns can be plural ("three apples go into the pie").
- If you have a combination of countable and uncountable, congratulations, you have a compound subject, and ergo a plural ("three apples and some flour go into the pie").
Your first example, "bread and butter," is a compound noun. Although the word "and" is included, it's treated as one thing ("gin and tonic is the best drink" "'Twist and Shout' is an over-rated song"). When you use them together you mean a different thing than when you use them separately. "Gin and tonic are both liquids"—that sentence is no longer talking about the same thing as "gin and tonic." So it's an equivocation to say that "bread and butter" can be either singular or plural. The same words can be used in a singular compound noun, or as two unrelated nouns on their own.
Solution 2:
If you have separate countable and/or uncountable nouns they take a singular verb if they are intended as a combination or are considered together as some kind of unit, be it food, things, actions, etc. Of course they take the usual plural when they are separate things. The nature of the nouns (countable or uncountable) really doesn't come into play.
