Can frequently yelling at your child and insulting them be abusive?

My father is a believer that only hitting is abuse and claimed he never abused me. However, he would yelled too much. It was scary.

He would get upset at trivial things and yelled and at times it would proceed with calling me stupid, idiot, etc. That sounded humiliating. Even though he never laid a hand on me, was that still abusive?

There were times he was in a better mood and be back to be the funny person but if he was moody, he would be a yeller and sometimes hurled out insults.
