Definition

1. Adjective:
   • Being three years of age: Describing a person, animal, or sometimes an object that has reached the age of three years.

Usage

• The adjective "three-year-old" is used attributively, meaning it typically comes before a noun to describe it. Note the use of hyphens to connect the words when used as a single descriptive term before a noun.

Examples
