Past Tense of Leave
“Leave” follows the pattern leave → left → left. The same inflected form serves a finite simple-past clause and a past-participle construction; surrounding grammar identifies the role. This guide covers the ordinary verb “leave.” Merriam-Webster separately records “leaved” for a distinct rare verb meaning to put forth leaves; do not use that separate sense to alter the ordinary leave → left → left paradigm.
The simple past and past participle of “leave” are both “left.”
