Picked up component for still (5)
I believe the answer is:
peace
'still' is the definition.
(I've seen this before)
'picked up component' is the wordplay.
'picked up' indicates a 'sounds like' (homophone) clue.
'component' becomes 'piece' (I've seen this before).
'piece' is a homophone of 'PEACE'.
'for' is the link.
(Other definitions for peace that I've seen before include "Repose, tranquillity" , "Caught" , "Quiet companion" , "A Christmas wish" , "Absence of war" .)
