Notice FT is torn up, producing bits of paper (8)
I believe the answer is:
confetti
'paper' is the definition.
(confetti is a kind of paper)
'notice ft is torn' is the wordplay.
'is torn' indicates anagramming the letters.
'notice'+'ft'='noticeft'
'noticeft' with letters rearranged gives 'CONFETTI'.
'up producing bits of' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for confetti that I've seen before include "cast only for union celebration" , "Small pieces of coloured paper" , "Celebratory scraps of coloured paper thrown at weddings" , "Throw it at the wedding, it's in bits" , "Scraps of coloured paper thrown in celebration" .)
