What are past participles?

Past participles are parts of verbs used to form many verb tenses. We use them to form the past perfect tense, present perfect tense, and future perfect tense, but what are they? Here are some examples.

Every verb has what are called four principal parts. This means that we can take any verb and break it into these parts. Past participles are simply one of those principal parts of a verb.

Here's a chart showing you some examples of verbs broken into their principal parts.

Present	Present Participle	Past
come	(is) coming	came	(have) come
fall	(is) falling	fell	(have) fallen
go	(is) going	went	(have) gone
graduate	(is) graduating	graduated	(have) graduated
know	(is) knowing	knew	(have) known
run	(is) running	ran	(have) run
write	(is) writing	wrote	(have) written

Here's some good news for you: Regular verbs follow a pattern! 

That's why they are called regular. If you have a regular verb, simply add -d or -ed to the present tense form of the verb.

Present Tense	+ d or ed
learn	+ ed		learned
spike	+ d		spiked
play	+ ed		played

Now, here's some bad news for you: Irregular verbs don't follow a pattern. This can make it hard to know the past participles of irregular verbs. But, know that you can always use a dictionary if you're unsure. You'll see some examples in this chart.

Present Tense	Change to ?
bring	brought		brought
build	built		built
win	won		won

When people talk about participles, they may be referring to something a little different from what we've covered on this page. They might be talking about something called a verbal. Verbals are verb forms that look like verbs but don't act like verbs.

Participles are a type of verbal that act like an adjective instead of a verb.

The running deer were beautiful! 

Running is a participle. It looks like a verb, but it acts like an adjective modifying the noun deer.

The burned toast tasted awful.

In this sentence, burned is a participle. It looks like a verb, but it acts like an adjective modifying the noun toast.
