Excellent guess (6)
I believe the answer is:
divine
I believe this is a double definition.
'excellent' is the first definition.
(thesaurus)
'guess' is the second definition.
(divining is a kind of guessing)
(Other definitions for divine that I've seen before include "wonderful" , "Godlike or extremely beautiful" , "Godlike (6" , "Find water" , "Godly or celestial" .)
