Earlier or in front of (6)
I believe the answer is:
before
I believe this is a double definition.
'earlier' is the first definition.
(synonyms)
'in front of' is the second definition.
(standing before means standing in front of)
(Other definitions for before that I've seen before include "Previously ? in front" , "During the period preceding" , "In sight of" , "Earlier than something" , "Prior to" .)
