A lot of threads get hijacked for spelling, grammar, word use, and definitions. Let it all out here instead.
Man can mean a male or a female. As in a member of mankind, or a woman. The first definition of man is an individual human; no note on sex. Another definition is the individual who can fulfill or who has been chosen to fulfill one’s requirements, with the example <she’s your man>.
A female actor is an actor. Yes, actress is a word, but it’s redundant. An actor is a person who acts, not a male who acts. In my Webster’s Unabridged, in the section advising how to avoid sexism in your writing, it specifically says “instead of actress, use actor.”
Jive is slang or music. When things agree, they jibe.
It’s is it is and nothing else. It is not the possessive form of it. That never made sense to me until someone pointed out that we don’t use an apostrophe in the possessive form of any pronouns in English. Towels are his and hers, not hi’s and her’s.
On that note, who’s is who is and nothing else. The possessive of that word is whose.
Just a note: none of this is worth fighting over. Language, especially English is highly open to interpretation; if someone calls a horse a pickle you’d think they were clearly wrong, but what if you knew exactly what they meant? They communicated effectively through language. I don’t see how that’s anything but correct. Stricter personal interpretations are acceptable, of course. If you want to cut someone’s tongue out when they say pacific but mean specific, I sympathize. Just please don’t do it here :).
