Western' culture's historical use of the word, where the word came from, etc.<quoted text>
YOUR historical use if the word.
Nope. Unless, by "talkerer," you mean "A profession is a vocation founded upon specialized educational training, the purpose of which is to supply objective counsel and service to others, for a direct and definite compensation, wholly apart from expectation of other business gain."It's just as much of an insult when you say I'm not a professional as when I call you a college talkerer.
But only a seriously stupid person would attempt to make such a poor argument since English already includes a word defined as that.
