Yes. There is. No, it wasn’t abuse.
Abuse is ongoing, systemic, and meant as derrogatory or “mean”.
You can redifne terms, like a good little Leftist, but don’t pretend it wins you the moral high ground.
I don't know why abuse must be “ongoing” to be categorized as abuse, but if you insist, here's a readjustment: assuming that your father just once beat you with a belt hard enough to leave black and blue marks for a week, then your father once assaulted and battered you. (By the way, legally, assault and battery does not have to be “ongoing” to qualify as assault and battery.”)
