Isn't bee in jade a colourful stinger? (9)
I believe the answer is:
paintball
'a colourful stinger?' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.
'isn't bee in jade' is the wordplay.
'isn't' becomes 'aint' (non-standard version of 'isn't').
'bee' becomes 'b'.
'in' means one lot of letters goes inside another.
'jade' becomes 'pall' (synonyms).
'aint'+'b'='aintb'
'aintb' put inside 'pall' is 'PAINTBALL'.
Can you help me to learn more?
(Other definitions for paintball that I've seen before include "simulated combat" , "war game" , "Missile used in war games" , "messy game" .)
