Get some sunshine, did you say? (5)
I believe the answer is:
raise
'get' is the definition.
(as in to raise or get money)
'some sunshine did you say?' is the wordplay.
'some sunshine' becomes 'rays' (sun rays).
'did you say?' shows a homophone (sound like).
'rays' is a homophone of 'RAISE'.
(Other definitions for raise that I've seen before include "rally" , "Wage increase" , "Pick up" , "Increase; elevate" , "Put up" .)
