Salvēte omnēs! Spērō vōs agere bene.

I’ve been getting back into Latin lately (mainly through Wheelock’s, I have a beginner level but I think I’m starting to build up a better foundation), and I’ve been trying to think and look up what some common expressions would have been in Latin, and I couldn’t really find much on how you’d say “I’m right.”
I found something on “You’re wrong” potentially being something along the lines of “erras” or “falsus es,” but I’d like to ask here as well.

Could anyone help me figure out a proper way (attested preferably, but otherwise just some conventional way perhaps) of saying “I’m right” and “I’m wrong”? Grātiās vōbis agō, valēte!

Salve VeroPrometheu. For “I’m right” you could say “haud erro,” or “id quod dico verum est” (“what I say is true”); and “me fallit” or “fallor” for “I’m wrong.” But a lot will depend on the context, and you can’t expect word-for-word renderings of English locutions to be truly equivalent.
