Definition of Compound Nouns

A compound noun is a noun that consists of two or more words joined together to create a new meaning. These words can be written as a single word, separate words, or hyphenated words.

• toothbrush → (tooth + brush) = an object used to clean teeth
• mother-in-law → (mother + in + law) = the mother of one’s spouse
• ice cream → (ice + cream) = a frozen dessert
