Requires guts on losing quarter final (7)
I believe the answer is:
entails
'requires guts on losing quarter final' is the definition.
'entails' can be an answer for 'requires' (I've seen this in another clue). I'm not certain of the 'guts on losing quarter final' bit.
'requires guts on losing quarter' is the wordplay.
'requires' becomes 'needs' ('need' can be a synonym of 'require').
'guts' says to take the centre (the insides of the word).
'on' is a charade indicator (letters next to each other).
'losing' becomes 'tails' (I am not sure about this - if you are sure you should believe this answer much more).
'quarter' becomes 'n'.
The central letter of 'needs' is 'e'.
'tails' after 'n' is 'ntails'.
'e'+'ntails'='ENTAILS'
Can you help me to learn more?
(Other definitions for entails that I've seen before include "Has as a direct consequence" , "limits of will" , "Has as a logical consequence" , "Involves, makes necessary" , "Necessitates" .)
