Try to get a tan (8)
I believe the answer is:
sunbathe
'try to get a tan' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for sunbathe that I've seen before include "lie exposed?" , "Bask in solar heat" , "Expose one's body in order to get a tan" , "Try to get a tan" , "Bask to bronze" .)
