Swimmer of questionable style? (6)
I believe the answer is:
mullet
This clue might be a double definition.
'swimmer' is the first definition.
(I know that mullet is a type of fish)
'questionable style?' is the second definition.
'mullet' can be an answer for 'style?' (I've seen this before). I am not certain of the 'questionable' bit.
'of' acts as a link.
Can you help me to learn more?
(Other definitions for mullet that I've seen before include "Starfish" , "Fish's name for a hairstyle" , "swimmer" , "Fish (red or grey)" , "Food fish - hairstyle" .)
