Spanish hero holding up love god (5)
I believe the answer is:
cupid
'love god' is the definition.
(I've seen this before)
'spanish hero holding up' is the wordplay.
'spanish hero' becomes 'cid' (I've seen this in another clue).
'holding' indicates putting letters inside.
'cid' enclosing 'up' is 'CUPID'.
(Other definitions for cupid that I've seen before include "Love-god" , "godlike figure" , "boy carrying offensive weapon" , "boy with little bow" , "Boy symbol of love" .)
