Jaunty, dashing (6)
I believe the answer is:
rakish
I believe this is a double definition.
'jaunty' is the first definition.
(I know that jaunty can be written as rakish)
'dashing' is the second definition.
(I know that dashing can be written as rakish)
(Other definitions for rakish that I've seen before include "Given to philandering" , "Disreputably dashing" , "Marked by unconventionality or disreputableness" , "Dashing, devil-may-care" , "Jaunty; fast-looking (boat)" .)
