In legal terminology, a person who cedes or transfers property, rights, or territory; the grantor in a cession.
From Latin cessor, derived from cedere ('to yield'). This technical legal term designates the party giving up something in a formal transfer, serving as the counterpart to cessionaire.
While cessionaire (the receiver) became the standard term, cessor (the giver) is rarer in modern English—which itself reveals whose role lawyers thought more important to name when drafting contracts and treaties.
