is there a term for words such as inflammable?

Words that mean the exact opposite of how they sound.

Extralegal: not legal

Inflammable: able to be set a flame.

Do you have any other suggestions?

Don’t “inflammable” and “flammable” mean the same thing?
- Yeah, but Inflammable sounds like it isn't flammable
- I was about to argue with you and toss out a bunch of ad hominems on you, but then I looked it up and by golly you’re right. I’m one of the 10,000 today it seems.
Not sure, but another example is "irregardless"
Shelled and unshelled mean the same thing, same with pitted and unpitted
