The burden we bear (4)

Ross

I believe the answer is:

onus

I believe this is a double definition.

'the burden' is the first definition.
('onus' can be a synonym of 'burden')

'we bear' is the second definition.
(we carry anything on us)

(Other definitions for onus that I've seen before include "Burden, duty" , "'Burden, load (4)'" , "Duty or responsibility" , "'Burden, of proof (4)'" , "Obligation - charge" .)

I've seen this clue in The Mirror and The Daily Express.
