Standing in a rank (6)
I believe the answer is:
status
I believe this clue is a double definition.
'standing' is the first definition.
(I've seen this before)
'a rank' is the second definition.
(I've seen this in another clue)
'in' acts as a link.
(Other definitions for status that I've seen before include "Facebook feature" , "Rank or standing in society" , "Class" , "Position in society etc" , "Situation as it was before" .)
