But he's an odd sort to get tanned (8)
I believe the answer is:
sunbathe
'sort to get tanned' is the definition.
I can't judge whether this defines the answer.
'but he's an odd' is the wordplay.
'odd' is an anagram indicator.
'but'+'hes'+'an'='buthesan'
'buthesan' anagrammed gives 'SUNBATHE'.
Can you help me to learn more?
(Other definitions for sunbathe that I've seen before include "Try to get a tan" , "become brown" , "Lie in the heat of a celestial body" , "Expose one's body in order to get a tan" , "Expose one's body in hot weather" .)
