A participle is a form of a verb that often works like an adjective to describe nouns. Many verbs have two main participles: a present participle (usually ending in -ing, like “running” or “thinking”) and a past participle (often ending in -ed or having another special form, like “finished” or “broken”).

When you say “the sleeping dog,” you're using the present participle of “sleep” to describe which dog you mean. When you say “the broken window,” you're using the past participle of “break” to describe the window. Notice how these verb forms now act like adjectives.

Participles also help build other verb tenses. In “I am reading a book,” the present participle “reading” combines with “am” to show ongoing action. In “She has written three stories,” the past participle “written” combines with “has” to show completed action.

Writers use participles to make sentences more efficient and interesting. Instead of writing “The boy who was tired fell asleep,” you can write “The tired boy fell asleep.” Instead of “After she completed her homework, Maria went outside,” you can write “Having completed her homework, Maria went outside.”

Understanding participles helps you recognize sentence patterns and write with more variety and precision.
