In plain English: Responsibility is when you have to take care of something or do something because it is your job.
"It is everyone's responsibility to keep their workspace clean."
Usage: Use responsibility to describe the duty you owe someone else when an action affects them, rather than simply owning your own choices. It often pairs with verbs like accept or take to show willingness to handle a specific task or outcome.
The word responsibility comes from combining the English words responsible and -ity, a formation that likely happened after its components were borrowed from French. Interestingly, later versions of this term in French and Italian actually imitated the English spelling rather than originating independently.
