Grammar: 'food' and 'clothes'

Do we use 'is' or 'are' with 'food' and 'clothes'? e.g. 'The food are / is in the fridge.' 'These are Tommy's clothes.' or 'This is Tommy's clothes.'

In English, there are 'countable' and 'uncountable' nouns.
Countable (or count) nouns are those that can be counted and which are distinguishable as separate entities. We can say one table, two tables, several tables, many tables. These nouns take definite and indefinite articles and admit a plural form.

Uncountable (or mass) nouns, on the other hand, are nouns that take 'zero article' (no article) and they do not have a plural form. These are nouns that cannot be identified as separate units but can be 'measured'. Examples of mass nouns are iron, butter, ink, sugar, money, and most abstract nouns (hope, help, perseverance, etc.). In English, we do not say 'a milk' or 'two milks', but 'some milk', 'a pint of milk', a 'bottle of milk', etc.

There are also nouns with 'dual class membership': they can be used as mass or count, depending on the context. Often, these nouns have a different meaning in the two classes:
"A glass (countable) is made of glass (mass)."
"The boy was threw a stone (countable) at a wall made of stone (mass)."

Yes, right, your sentences are correct.

"Use" is subject, so it should be "is".
