Tanner requiring treatment for heat burns? (9)
I believe the answer is:
sunbather
'tanner' is the definition.
(I've seen this before)
'treatment for heat burns?' is the wordplay.
'treatment for' indicates anagramming the letters (I've seen this in other clues).
'heat'+'burns'='heatburns'
'heatburns' with letters rearranged gives 'SUNBATHER'.
'requiring' acts as a link.
(Other definitions for sunbather that I've seen before include "Tanner" , "One hoping for a tan" , "Loafer on the beach" , "One trying to get brown" , "One enjoying holiday" .)
