Question

Is the word "underwear" singular or plural?

Would you say "These ARE my underwear," or would you say, "These IS my underwear"?

Answer 1

Singular.

Explanation:

One would say, "this is my underwear." When referencing underwear in the plural, never say "underwears"--it's not a word. Instead, say "I'll need four pairs of underwear for my business trip."
