Gibe involving a daughter of doubtful honesty (5)
I believe the answer is:
shady
'of doubtful honesty' is the definition.
(I've seen this before)
'gibe involving a daughter' is the wordplay.
'gibe' becomes 'shy' (I am not sure about this - if you are sure you should believe this answer much more).
'involving' indicates putting letters inside.
'a daughter' becomes 'ad' (I've seen this in other clues).
'shy' placed around 'ad' is 'SHADY'.
Can you help me to learn more?
(Other definitions for shady that I've seen before include "Of questionable morality out of the sunlight" , "Of doubtful legality" , "Of dubious legality" , "Disreputable -- out of the sun" , "Of doubtful honesty" .)
