Note before la (3)
I believe the answer is:
sol
'note before la' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sol that I've seen before include "Fifth note of scale" , "Peruvian currency; Roman sun god" , "Spanish and poetic sun" , "Note, old french coin" , "Roman counterpart of Helios" .)
