1. To denigrate, to speak ill of or disrespectfully. To mock or criticize. Frequently in contracts there may be a non-disparagement clause which prevents a party from making denigrating, embarassing or negative comments about the other party in public. 2. An injury by union or comparison with some person or thing of inferior rank or excellence; as, while the infant was in ward, by the English law, the guardian had the power of tendering him a suitable match without disparagement.
