1. Attribute, ascribe, impute imply definite origin. Attribute and ascribe are often used interchangeably, to imply that something originates with a definite person or from a definite cause. Ascribe, however, has neutral implications; whereas, possibly because of an association with tribute, attribute is coming to have a complimentary connotation: to ascribe an accident to carelessness; to attribute one's success to a friend's encouragement. Impute has gained uncomplimentary connotations, and usually means to accuse or blame someone or something as a cause or origin: to impute an error to him. 5. See quality.
