Synonyms: help, aid, assist, succor
These verbs mean to contribute to the fulfillment of a need, the furtherance of an effort, or the achievement of a purpose or end. Help and aid, the most general, are frequently interchangeable: a medication that helps (or aids) the digestion. Help, however, sometimes conveys a stronger suggestion of effectual action: I'll help you move the piano. Assist usually implies making a secondary contribution or acting as a subordinate: Apprentices assisted the chef in preparing the banquet. Succor refers to going to the relief of one in want, difficulty, or distress: “Mr. Harding thought... of the worn-out, aged men he had succored” (Anthony Trollope). See also synonyms at improve
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.
