How it hurt dad to upset Enid (6)

I believe the answer is:
pained
'how it hurt' is the definition.
I can't judge whether this definition defines the answer.
'dad to upset enid' is the wordplay.
'dad' becomes 'pa' (pa can mean someone's father).
'to upset' indicates anagramming the letters.
'enid' with letters rearranged gives 'ined'.
'pa'+'ined'='PAINED'
Can you help me to learn more?
(Other definitions for pained that I've seen before include "Distressed or hurt in feelings" , "Distressed and annoyed - hurted" , "Caused suffering to" , "Caused hurt." , "Hurt and disapproving (6)" .)
