Swimmer has flaming ridiculous hairstyle (3,6)
I believe the answer is:
red mullet
'swimmer' is the definition.
(red mullet is a kind of fish)
'flaming ridiculous hairstyle' is the wordplay.
I cannot really understand how this works, but
'hairstyle' could be 'mullet' (I've seen this before) and 'mullet' is present in the answer.
The remaining letters 'red' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
'has' acts as a link.
Can you help me to learn more?
(Other definitions for red mullet that I've seen before include "Tasty swimmer" , "There's something fishy" , "one's gathered in net" , "Brightly coloured food fish" , "Fish -- dull meter (anag)" .)
