Carrying too much weight and imperious (11)

I believe the answer is:
overbearing
'imperious' is the definition.
(I've seen this before)
'carrying too much weight' is the wordplay.
'carrying' is a charade indicator (letters next to each other) (in a down clue, the bottom letters carry others).
'too much' becomes 'over' (over can mean to too great an extent).
'weight' becomes 'bearing' (I am not sure about this - if you are sure you should believe this answer much more).
'over' put next to 'bearing' is 'OVERBEARING'.
'and' is the link.
Can you help me to learn more?
(Other definitions for overbearing that I've seen before include "Officious" , "Imperious" , "Forceful in character" , "High-handed" , "Unpleasantly dominating" .)
