Noisy when we turn up? Not a lot! (3)
I believe the answer is:
few
'not a lot' is the definition.
(I've seen this in another clue)
'noisy when we turn up?' is the wordplay.
I cannot quite understand how this works, but
'noisy' could be 'f' and 'f' is present in the answer.
'when' could be 'e' (I've seen this in other clues) and 'e' is located in the answer.
A single letter 'w' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for few that I've seen before include "'''Many are called but ... are chosen'' (Bible) (3)'" , "Indefinite small amount" , "Considerable number, ironically" , "Relatively small number" , "Only one or two" .)
