Definition
A concessor is a grantor — a party who conveys or transfers an interest in property to another. The term appears in old English law as the Latin designation for the transferring party in a grant, corresponding to the modern grantor in a deed or conveyance.
Common Language
Modern common usage (Wiktionary): A person who concedes.
Historical common usage (Webster's 1913): Not separately defined; derived from the verb "concede," meaning to yield or grant.
The ordinary English sense of "concede" carries connotations of reluctant yielding or admission. The legal term concessor carries none of that coloring — it simply identifies the party who makes a grant, without any implication of dispute or surrender.
Common Confusion
Concessor and grantor are functionally synonymous, but they are not interchangeable in research. Concessor is Latin-origin terminology tied to medieval and early English conveyancing forms. When historical sources use concessor, they are operating within a formal Latin pleading or deed tradition. Modern instruments use grantor exclusively. A researcher who encounters concessor in a historical document should not assume any substantive distinction from grantor, but should recognize the document's age and formal register accordingly.
Why It Matters in Research
This term is a navigational marker more than a substantive concept. Its presence in a legal instrument or pleading is strong evidence of age — concessor belongs to a tradition of Latin conveyancing vocabulary that receded as English became the standard language of legal documents.
Researchers working in the Law Mind corpus should treat concessor as a signal to look for related archaic conveyancing vocabulary in the same document: concedere (to grant), concessio (the grant itself), and concessus (granted). These terms travel together in old English and early colonial deed forms, and understanding one often requires understanding the cluster.
The term also appears in pleading contexts, not only in deeds. Burrill cites Townshend's Pleadings, situating concessor within the formal structure of actions involving grants — where identifying the party who made the grant (the concessor) was a pleading requirement. Researchers examining early common law pleading records may encounter the term in that procedural frame rather than in a transactional instrument.
No significant evolution of meaning to track: concessor meant grantor when it entered English legal usage and meant grantor when it fell out of use. The research trap is not definitional drift but simple unfamiliarity — a researcher unaware of the term may fail to recognize it as a party designation and misread the document's structure.
Historical Dictionary Support
The historical dictionaries are in complete agreement: every source defines concessor simply as "a grantor" and flags it as old English law terminology. Black's Law Dictionary (both editions), Bouvier's, and Burrill's all give the same one-line definition with no substantive variation.
Burrill alone adds the Latin derivation (concedere, to grant) and the citation to Townshend's Pleadings, which is useful context. The citation grounds the term in pleading practice specifically, suggesting that concessor had a procedural life beyond deed drafting.
No historical dictionary identifies any nuance, regional variation, or evolution of meaning. For this term, the historical sources are reliable as far as they go — but they go only as far as a cross-reference. The researcher's work is not in reconciling competing definitions but in recognizing the term on sight and understanding its documentary context.
Jurisdictional Note
Concessor is a term of English legal origin with no meaningful jurisdictional variation in the American context. Early American deeds and pleadings that use the term are drawing directly from English practice. It does not appear in modern statutory or regulatory usage in any jurisdiction.
