gigno

Gigno, gignere, genui, genitum is third conjugation, and the present stem is a reduplicated form of the root gen- that shows up plainly in the perfect and supine. So the four parts share a root you cannot see in the first of them, which is why gigno and genuit look like different verbs. Same family as genus, gens, ingenium and English genesis.

It is transitive and active, the parent's verb: the father or mother gignit, the child nascitur. That pairing with the deponent nascor is the neat bit of the system, one act described from each end. The perfect participle genitus therefore means "born" or "begotten", and in the creed genitum non factum, "begotten not made", turns on exactly that distinction. Extended to any producing: the earth gignit crops, causes gignunt wars.
