Regular visitor somewhat put in shade (7)
I believe the answer is:
habitue
'regular visitor' is the definition.
(I've seen this before)
'somewhat put in shade' is the wordplay.
'somewhat' becomes 'a bit' (a bit).
'put in' is an insertion indicator.
'shade' becomes 'hue' (both can mean a colour).
'abit' going inside 'hue' is 'HABITUE'.
(Other definitions for habitue that I've seen before include "Frequent visitor to a place" , "Constant visitor" , "Regular customer" , "Person who visits a place frequently, may live there" , "One of the regulars" .)
