Female setter has X factor (4)
I believe the answer is:
five
'x factor' is the definition.
The answer and definition can be both quantities as well as being singular nouns.
Perhaps you can see a link between them that I can't see?
'female setter has' is the wordplay.
'female' becomes 'f' (common abbreviation).
'setter has' becomes 'I've' ('I have' referring to the crossword setter).
'f'+'ive'='FIVE'
Can you help me to learn more?
(Other definitions for five that I've seen before include "Number of towns Arnold Bennett's Anna is associated with" , "Quintet" , "Cube root of 125" , "Odd number" , "Enid Blyton's famous number?" .)
