Compound nouns

A compound noun is a noun made with two or more words. A compound noun can be formed by:

a) Noun + Noun
= head + board = headboard
b) Adjective + Noun
= black + board = blackboard

Three types of compound nouns:

A single word: These nouns are written together.

pillow + case
= pillowcase
bed + spread
= bedspread


Two words: These nouns are written separated.

twin + bed
= twin bed
alarm + clock
= alarm clock


Hyphenated: These nouns are written together connected with the symbol “-” hyphen.

queen + size
= queen-size
king + size
= king-size


Note: Sometimes the hyphenated type becomes an adjective, so you need a noun.
