Today we will learn about compound nouns.

Compound nouns are words that consist of two or more words that are join together to make a single noun.

Compound nouns usually are formed by nouns plus nouns or adjectives or prepositions or verbs.

Compound nouns are expressed in three ways:

1. Closed form: the words are written as a single word (no space)

E.g. 

a. Makeup: A smile is the best makeup any girl can wear.

b. Bedroom: If you’d like to stay, we got a spare bedroom for you.

c. Notebook: Suzan brought out a notebook to study at library.
2. Hyphenate form: the words are written with hyphen between words

E.g. 

a. Sister-in-law: My sister-in-law stared at her reflection in the mirror.

b. Six-pack: Harry got a six-pack in eight weeks.

c. Three-year-old: Gwen articulates well for a three-year-old kid.
3. Closed form: the words are written with a space between words

E.g. 

a. Post office: Look straight ahead and you will see the post office.

b. Sleeping bag: The sleeping bag is very warm.

c. First aid: Did you learn any first aid at school?
