[I]t would be kind of silly to say that therefore coinages like “chocoholic” are illegitimate or wrong. It would be a little like saying the expression “the algorithm” is wrong because the “al” in “algorithm” historically comes from a definite article, making the “the” redundant.
Or, at the very least, the time to object to “chocoholic” would have been when the word was first being used. Now that it’s caught on, it’s too late.
Our beloved Redneck Diva begs to differ with Mr Beavispants:
If someone wanted to declare themselves addicted to chocolate they would be a chocolatic. Or perhaps a chocolic. A person who likes to shop is a shoppic.
Make note of it.
