Absent father meets your total indifference (6)
I believe the answer is:
apathy
'total indifference' is the definition.
'apathy' can be an answer for 'indifference' (synonyms). I'm not sure about the 'total' bit.
'absent father meets your' is the wordplay.
'absent' becomes 'a' (this might be a standard abbreviation of which I'm unaware).
'father' becomes 'pa' (pa can mean dad or father).
'meets' says to put letters next to each other.
'your' becomes 'thy' (I've seen this before).
'a'+'pa'+'thy'='APATHY'
Can you help me to learn more?
(Other definitions for apathy that I've seen before include "Indifference - listlessness" , "Detachment" , "Indifferent quality" , "Complete lack of interest, indifference" , "Absence of interest or emotion" .)
