May be silent, but it looks good (6)
I believe the answer is:
tinsel
'it looks good' is the definition.
The definition suggests a singular noun which matches the answer.
'may be silent' is the wordplay.
'may be' indicates anagramming the letters.
'silent' is an anagram of 'TINSEL'.
'but' acts as a link.
Can you help me to learn more?
(Other definitions for tinsel that I've seen before include "Christmas decorations" , "Christmas tree decoration" , "Glittering metal foil strip" , "23 across (anag)" , "Sparkly strands" .)
