What you'll learn
By the end of this lesson, you'll be able to use past participle (-ed) clauses to express passive ideas concisely.
When do I use it?
A past participle clause uses -ed forms (or irregular participles like broken, written) to describe something that happens TO the subject, not something the subject does:
- Reason: "Surprised by the news, she called her mother." (= Because she was surprised...)
- Passive + reduced relative: "The letter, written in 1920, is now in a museum." (= which was written in 1920)
It is the passive twin of the present participle clause: use -ing when the subject does the action, -ed when the subject receives it.
How do I form it?
-ed clause, + main clause noun + -ed clause (reduced relative)
- Exhausted after the trip, he slept for twelve hours.
- Worried about her son, she stayed at home.
- The house, built in 1900, is still in perfect condition.
- Given more time, we could have finished.
Common mistakes for Spanish speakers
Spanish speakers confuse -ed and -ing participle adjectives ("interesado" vs "interesante"): "surprised" (I feel it) vs "surprising" (it causes the feeling). A past participle clause describes a passive relationship, so "broken by the storm, the window..." is fine, but do not use -ed where the subject acts: "writed" is wrong spelling, and "the man, written the letter, left" is wrong — the man WRITES, so use "writing the letter". Only -ed for the receiver.
-ed = the subject receives the action (passive feel). -ing = the subject does the action.
