Bearing, manner (4)
I believe the answer is:
mien
This clue is a double definition.
'bearing' is the first definition.
(I know that bearing can be written as mien)
'manner' is the second definition.
(mien can mean a manner or attitude)
(Other definitions for mien that I've seen before include "Counterance - mine?" , "The carriage" , "attitude" , "Person's appearance or manner" , "Dignified manner" .)
