Past Tense of Fight
“Fight” is irregular: fight → fought → fought. The same inflected form serves a finite simple-past clause and a past-participle construction; grammar and surrounding auxiliaries identify the role. The same form applies to physical combat and figurative struggle; the sense changes, but the conjugation does not.
The simple past and past participle of “fight” are both “fought.”
