Intelligence required to get round a delay (4)
I believe the answer is:
wait
'delay' is the definition.
(I know that delay is a kind of the wait)
'intelligence required to get round a' is the wordplay.
I cannot really understand how this works, but
'a' is within the answer.
'intelligence' could be 'wit' (wit is a kind of intelligence) and 'wit' is present in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for wait that I've seen before include "Delay, stand by" , "Period of delay" , "Serve at table" , "Hang about" , "singer" .)
