A personal assistant gets over your indifference (6)
I believe the answer is:
apathy
'indifference' is the definition.
(I know that indifference can be written as apathy)
'a personal assistant gets over your' is the wordplay.
I cannot really understand how this works, but
'a' is present in the answer.
'assistant' could be 'pa' (personal assistant) and 'pa' is located in the answer.
'your' could be 'thy' ('thy' historically meant 'your') and 'thy' is located in the answer.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for apathy that I've seen before include "Lack of interest in things in general" , "Detachment" , "Absense of interest or emotion" , "Lack of emotion and enthusiasm" , "Flatness" .)
