How do you conjugate conjuguer in the past progressive tense in french?

Answer 1

I assume what you call past progressive tense is that we French call passé composé.
J'ai conjugué
tu as conjugué
il / elle a conjugué,
nous avons conjugué,
vous avez conjugué,
ils / elles ont conjugué.

Answer 2

To conjugate "conjuguer" in the past progressive tense in French, you would use the auxiliary verb "être" in the imperfect tense followed by the present participle of "conjuguer," which is "conjuguant." For example, "J'étais en train de conjuguer" means "I was conjugating."
