He gives us a beam (3)
I believe the answer is:
ray
I believe this is a double definition.
'he' is the first definition.
'a beam' is the second definition.
(synonyms)
'gives us' is the link.
(Other definitions for ray that I've seen before include "Beam - skate" , "A bright beam or flat fish" , "Beam or flatfish" , "Lindwall" , "Gleam" .)
