The word infamous is misused so often on Yahoo! that I am beginning to think maybe it is synonymous with famous, kind of like flammable and inflammable are synonyms. This time the misuse is on Yahoo! Screen:
Unless Ms. Smith’s job involves something heinous or notorious, I don’t think it’s infamous. It may not even be famous.

You’d think she’d be in hiding, what with an infamous job and all.
PS: I found another word where it and its “in” version are synonymous: habitable and inhabitable. (I don’t think there’s an “unhabitable”.)
