Listen out for trimming (6)
I believe the answer is:
tinsel
'trimming' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'listen out' is the wordplay.
'out' indicates an anagram (out can mean wrong or inaccurate).
'listen' anagrammed gives 'TINSEL'.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for tinsel that I've seen before include "Sparkly strands" , "Strip of glittering paper" , "Listen (anag) - something cheap and showy" , "Sparkly decoration" , "Gaudy decoration" .)
