Perhaps fighter needs to display cunning (8)
I believe the answer is:
aircraft
'perhaps fighter needs' is the definition.
I can't tell whether this defines the answer.
'display cunning' is the wordplay.
'display' becomes 'air' (air can mean to display or show something).
'cunning' becomes 'craft' (cunning can mean craftiness).
'air'+'craft'='AIRCRAFT'
'to' is the link.
Can you help me to learn more?
(Other definitions for aircraft that I've seen before include "High-flier" , "Aeroplane, helicopter etc" , "Airbus A380 or Boeing 747 say" , "Airbus A330 or 380, say" , "means of transport" .)
