English language debate...?
I am wondering two things. One is a mere question of the English language. The other is a polite debate between my wife and I. First of all, why is it that "thaw" and "unthaw" mean the same thing, when, in just about every other case in English, the prefix "un-" describes the opposite of the word it precedes? Secondly, which word do you more commonly use, "thaw" or "unthaw?"
