Disdainful means showing that you consider something beneath you. The look, rather than the argument.
It takes of. The word describes manner above all, so a disdainful glance, a disdainful sniff and a disdainful tone are its natural homes. What separates it from contemptuous is temperature, since disdain is cool and contempt is hot. Cats are described as disdainful more often than any other animal, and the word suits them. The noun is disdain and the verb means to reject something as unworthy.
