Past Tense of Dig
“Dig” follows the pattern dig → dug → dug. The same inflected form serves a finite simple-past clause and a past-participle construction; surrounding grammar identifies the role. For ordinary modern use in the reviewed evidence, the paradigm is dig → dug → dug; do not invent “digged” without separate sense-specific evidence.
The simple past and past participle of “dig” are both “dug.”
