Refurbish Christmas tree after removing torn chits and pennant (8)
I believe the answer is:
streamer
'pennant' is the definition.
(synonyms)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for streamer that I've seen before include "It blows in the wind" , "Long flag, tapering perhaps" , "Long narrow ribbon for er, master" , "Heavy cold" , "shocking cold?" .)
