Past Tense of Set
“Set” follows the pattern set → set → set. The same inflected form serves a finite simple-past clause and a past-participle construction; surrounding grammar identifies the role. The verb is zero-change across base form, simple past, and past participle; the present participle is “setting.” Noun and adjective senses of “set” are separate.
The simple past and past participle of “set” are both “set.”
