What is a synonmy for gloat?

Synonyms are words that generally mean the same thing, for example nice and kind. Although they may have slightly different meanings and connotations, those two words pretty much have the same...

A Synonym is something that is related to another word. Like a Synonym for crazy could be mad, insane, weird, nutty, bizzare. An Antonym is the oppisite. For crazy and antonym is sane, level- headed.

Feeling, or emotion, maybe?

No. I'd say the only living thing capable of such a specific emotion would be a human being.

Bragging. My dad can beat up your dad. My kid is smarter than your kid. My car is nicer than his car. Or, having more money than someone else & bragging about it.
