God is hurt, abandoned by one (3)
I believe the answer is:
pan
'god' is the definition.
(Pan is an example)
'hurt abandoned by one' is the wordplay.
'hurt' becomes 'pain' (paining is a kind of hurting).
'abandoned by' is a deletion indicator.
'one' becomes 'i' (Roman numeral).
'pain' with 'i' removed is 'PAN'.
'is' acts as a link.
(Other definitions for pan that I've seen before include "Cooking utensil and Greek god" , "Cooking container; god" , "Severely criticise; god" , "God of herds with merry merry pipes" , "all in many words, initially" .)
