Dad's turn to indicate name for an office (7)
I believe the answer is:
appoint
'name for an office' is the definition.
I can't judge whether this defines the answer.
'dad's turn to indicate' is the wordplay.
'dad' becomes 'pa' (both can mean one's father).
'turn' shows that the letters should be reversed in order.
'to indicate' becomes 'point' ('point' can be a synonym of 'indicate').
'pa' backwards is 'ap'.
'ap'+'point'='APPOINT'
Can you help me to learn more?
(Other definitions for appoint that I've seen before include "Assign position to" , "Designate (job)" , "Assign to a duty" , "Officially assign" , "Pick" .)
