compound nouns

Two-word noun phrases

A compound noun is a noun formed from two or more words functioning as a single unit: toothbrush, ice cream, mother-in-law.

Compounds may be written as one word, hyphenated, or separate words—conventions vary and shift over time.

The stress typically falls on the first element: BLACKbird (the species) versus black BIRD (any bird that's black).
