Rather Flo than Dicky (3,4)
I believe the answer is:
not half
'rather' is the definition.
(I've seen this before)
'flo than dicky' is the wordplay.
'dicky' indicates anagramming the letters (dicky can mean not functioning properly).
'flo'+'than'='flothan'
'flothan' is an anagram of 'NOT HALF'.
(Other definitions for not half that I've seen before include "Very much, exceedingly" , "Oh, yes!" , "Absolutely (but less than 50%!)" , "unequal share for you or me" , "Very much (but less than 50%)!" .)
