Dismissive means treating something as not worth considering. A wave of the hand and a change of subject.
It takes of: dismissive of the idea, dismissive of her concerns. The word describes manner as much as opinion, since being dismissive is about refusing the argument rather than losing it. A dismissive gesture, a dismissive tone, a dismissive shrug. It sits close to disdainful but is more common and less grand. The verb dismiss means to send away, to reject an idea, and to sack somebody from a job.
