Is held by a goddess to be improper employment (6)
I believe the answer is:
misuse
'improper employment' is the definition.
'misuse' can be an answer for 'employment' (I have seen 'Wrongful employment' mean 'misuse' so perhaps 'employment' could also mean 'misuse'). I am not certain of the 'improper' bit.
'is held by a goddess' is the wordplay.
'held by' indicates putting letters inside.
'a goddess' becomes 'muse' (I've seen this in other clues).
'is' inserted within 'muse' is 'MISUSE'.
'to be' is the link.
Can you help me to learn more?
(Other definitions for misuse that I've seen before include "exploitation" , "Apply badly or incorrectly" , "Treat badly, unfairly" , "harm" , "bad practice" .)
