Bides one's time (5)
I believe the answer is:
waits
'bides one's time' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for waits that I've seen before include "Carol singers" , "Seasonal singers" , "Lingers" , "Itinerant carol-singers" , "Night-time Yuletide singers" .)
