Unwise to be cheeky without a right (9)
I believe the answer is:
imprudent
'unwise' is the definition.
(similar in meaning)
'cheeky without a right' is the wordplay.
I cannot really see how this works, but
'right' could be 'r' (common abbreviation) and 'r' is present in the answer.
'cheeky' could be 'impudent' (I've seen this before) and 'impudent' is located in the leftover letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'to be' is the link.
Can you help me to learn more?
(Other definitions for imprudent that I've seen before include "Unwise" , "Incautious" , "Reckless" , "Lacking in good sense or caution" , "not wise" .)
