Below, under (7)
I believe the answer is:
beneath
I believe this clue is a double definition.
'below' is the first definition.
(synonyms)
'under' is the second definition.
(under means beneath or underneath)
(Other definitions for beneath that I've seen before include "At a lower place" , "in a lower position" , "Directly under" , "At a lower level (than)" , "Inferior to" .)
