Responsibility we must meet? (4)
I believe the answer is:
onus
'responsibility' is the definition.
(onus is a duty or responsibility)
'we must meet?' is the wordplay.
'we' becomes 'us'.
'must' becomes 'on' (I can't justify this - if you can you should believe this answer much more).
'meet?' says to put letters next to each other.
'us' put after 'on' is 'ONUS'.
Can you help me to learn more?
(Other definitions for onus that I've seen before include "Burden, duty" , "albatross?" , "'Burden, of proof (4)'" , "Duty or responsibility" , "Responsibilty" .)
