Supporting a certain direction (7)
I believe the answer is:
bearing
This clue might be a double definition.
'supporting' is the first definition.
(similar in meaning)
'a certain direction' is the second definition.
'bearing' can be an answer for 'direction' (bearing is a kind of direction). I am unsure of the 'a certain' bit.
Can you help me to learn more?
(Other definitions for bearing that I've seen before include "Mien; carrying" , "Giving birth" , "Compass point" , "Carriage; relevance" , "Carriage; suffering" .)
