Smart force ten gale (7)
I believe the answer is:
elegant
'smart' is the definition.
(similar in meaning)
'force ten gale' is the wordplay.
'force' indicates an anagram (letters must be forced into a new order).
'ten'+'gale'='tengale'
'tengale' with letters rearranged gives 'ELEGANT'.
(Other definitions for elegant that I've seen before include "Refined and dignified in appearance" , "Dignified and graceful" , "Fine" , "Attractive and graceful or stylish" , "Polished" .)
