>"Recur" is a poor synonym for the meaning intended by "recurse", because it fails to make the essential distinction between iteration and recursion. Unpleasant as it may be to your ear, "recurse" is pretty widely accepted in programmer parlance, for lack of an adequate alternative.

Well, it may be widely used (abused, in my view) by programmers, but a search on Dictionary.com turns up "recurse" only in "The Free Online Dictionary of Computing," in other words, in an informal dictionary. OTOH, "recursion" is identified as the past participle of "recur."

People misuse the language all the time; that doesn't make them right. (Yes, I know that language evolves and eventually a misuse can be a proper use, but there's a long period before that when wrong is just wrong.) We discussed "I could care less" here recently. It doesn't matter how many people write it that way; that's still incorrect use of the phrase "I couldn't care less."

Bottom line for me: When I edit something that has "recurse," I will change it. When I read something using "recurse," it will lower my opinion of the writer.
