Note the Sun (3)
I believe the answer is:
sol
I believe this is a double definition.
'note' is the first definition.
(I've seen this before)
'the sun' is the second definition.
(thesaurus)
(Other definitions for sol that I've seen before include "Fifth note of scale" , "The sun in Spain" , "Musical note" , "Note - colloid - the Sun" , "Personification of the sun" .)
