Usage note:
An early and still the most current sense of deprecate is “to express disapproval of.” In a sense development still occasionally criticized by a few, deprecate has come to be synonymous with the similar but etymologically unrelated word depreciate in the sense “belittle”: The author modestly deprecated the importance of his work. In compounds with self-, deprecate has almost totally replaced depreciate in modern usage: Her self-deprecating account of her career both amused and charmed the audience.
