Ending a word with the wrong suffix

I have heard a term used to describe when someone ends a word with the wrong suffix. I can only think of the word "conversate" instead of "converse" though both might actually be perfectly fine.

Maybe a better example is if someone were to say that something is very "benefiting" instead of "beneficial."

Can you help?

Thanks,
Ari

Hmmm. The closest that I can come up with is "pseudography".
