This was my Google Home Page's Word of the Day:
|jaunty||(adjective) Having a cheerful, lively, and self-confident air.|
|Usage:||He moved very quickly, and there was an air of jaunty liveliness about him.|
If you use lively in the definition, is it really necessary to use it in the sentence as well? Perhaps a better option would have been: He moved very quickly, and there was a jaunty air about him.
Just a small pet peeve for your contemplation...
