Past Tense of Flee
“Flee” follows the pattern flee → fled → fled. The same inflected form serves a finite simple-past clause and a past-participle construction; surrounding grammar identifies the role. Do not regularize the verb as “fleed”; the reviewed authorities give “fled” for both past roles.
The simple past and past participle of “flee” are both “fled.”
