A catchy non-U tune, possibly? (3)
I believe the answer is:
net
'a catchy' is the definition.
I can't judge whether this defines the answer.
'non-u tune possibly?' is the wordplay.
'non' is a deletion indicator.
'possibly?' indicates an anagram (I've seen 'possibly' mean this).
'tune' with 'u' removed is 'tne'.
'tne' anagrammed gives 'NET'.
Can you help me to learn more?
(Other definitions for net that I've seen before include "Open mesh; catch" , "Open-mesh material" , "Butterfly trap" , "Final profit when all overheads have been deducted" , "Catch, ensnare" .)
