Thanks very much for the advice, Jackie! I'll definitely know how to make a clickable URL from now on.

You may be a little mystified by the political aspect of the debate on that page. You see, on the one hand you have the Protestants saying that the word comes into English from Ulster-Scots (a dialect of English, or of Scots, or a distinct Germanic language, depending on whom you talk to). On the other hand you have Catholics saying it was adopted into English from Irish. Each side accuses the other of trying to "claim the word for themselves" in a bizarre form of one-upmanship. Even the existence of the Ulster-Scots language ("Ullans") is a political issue, with Catholics saying the Protestants are only pretending to have their own language to achieve "parity of esteem" with the Catholics (who supposedly own the Irish language). I have little doubt that we will end up with Catholics writing "craic" and Protestants writing "crack", to add to all the other shibboleths with which the people like to distinguish themselves from their neighbours.

If this all sounds a little silly to you, welcome to political discourse, North of Ireland style!
