1. What Are Compound Nouns?

Compound nouns are nouns made up of two or more words that come together to form a single noun with a new meaning. The words in a compound noun can be either combined with a hyphen or written as one word without any punctuation. The combination of words creates a unique noun that represents a specific object, person, or concept.

Examples:

  • Hyphenated Compound Nouns:
    • brother-in-law, mother-in-law, six-year-old, well-known
  • Closed Compound Nouns (written as one word):
    • keyboard, notebook, bedroom, sunlight
  • Open Compound Nouns (written as separate words):
    • post office, high school, swimming pool, traffic light
