verb helped, help·ing, helps verb, transitive
Origin: Middle English helpen
Origin: , from Old English helpan. Usage Note: Many people commonly use help in the sense conveyed in the sentence Don't change it any more than you can help (that is, “any more than you have to”). Some grammarians condemn this usage on the grounds that help in this sense means “avoid” and therefore logically requires a negative. But the expression is a well-established idiom.
