Lumbago for Greek god? (4)
I believe the answer is:
eros
'greek god?' is the definition.
(Eros is an example)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for eros that I've seen before include "capital statue" , "Arrow-shooting god" , "divinity" , "Greek equivalent to Roman Cupid" , "Asteroid - Greek god of love" .)
