COMPOUND NOUNS

Definition :
When we put two or more words together to create a new word, we have made a compound noun.

Nouns of more than one word are called compound nouns.

e.g.

noun + noun police officer ice-creamfirefighter
noun + verb carwash haircut milkshake
verb + noun cross-road cookbookjump rope
adjective + noun black eye blue jeans hotdog
adverb + noun on-lookerdowntime overtime
adverb + verb input output upswing

Compound nouns can take three forms: hyphenated, solid and open.

HYPHENATED COMPOUNDS

When two or more words are connected by one or more hyphens, the result is a hyphenated compound. Some compound words are hyphenated to avoid being misread or ambiguous.

e.g.

sister-in-lawjack-in-the-boxstate-of-the-art
shout-outmind-setfive-year-old

SOLID COMPOUNDS

Solid compounds are words that are used as a single unit of meaning and it is closed up as solid, or closed, compounds.

e.g.

rollbackrestroomwhatever
breakfastneedlepointslingshot

OPEN COMPOUNDS

Sometimes no hyphenating or closing up is necessary to form a compound. Open compounds are words that are used as a single unit of meaning but are still written separately as two words.

e.g.

wet nurseroller coasterwhatever
sleeping bagfirst aid mug shot
