To officially repeal, do away with, or put an end to a law, right, or agreement.
From Latin 'abrogare' (to repeal), combining 'ab-' (away, off) + 'rogare' (to ask, propose). Originally meant to reject a proposal; evolved to mean canceling laws or formal agreements.
When a government 'abrogates' a treaty, it's literally saying 'no' to what previous leaders agreed to—a word that captures political defiance and the power to unmake decisions.
