because words can only mean one thing Yes, definitions change, but that's sort of a reductionist statement. I could make an equally reductionist point about the acceptance of non-standard usage based on the fact two definitions of "nonplussed" are opposites. Nonplussed means not nonplussed. I don't even think it would be hyperbolic to say the utility of using "hack" or "hacker" in a sentence has plummeted over the last decade because of it's everexpanding meaning.
