Enjoy the sun (4)
I believe the answer is:
bask
'enjoy the sun' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for bask that I've seen before include "Soak up sun" , "revel" , "Sun oneself (like a kind of shark?)" , "Lie in sunshine" , "Lie in the sun" .)
