Definition
A Latin term appearing in old legal records meaning to adjoin or border upon. Used in medieval and early English land records to describe the geographic relationship between parcels of land or territories — specifically, that one piece of ground abuts, is contiguous to, or shares a boundary with another. The term is essentially a verb form expressing adjacency or contiguity of land.
Why It Matters in Research
MARCHIARE is a term researchers will encounter almost exclusively in medieval Latin land records, including surveys, charters, and inquisitions post mortem. Its significance is narrow but specific: when a historical document uses this term, it is establishing a boundary relationship between two named properties or territories, not describing ownership, tenure, or any legal right. Misreading the term as indicating a possessory or administrative connection rather than a purely geographic one will distort interpretation of the document.
The term belongs to a cluster of boundary and adjacency vocabulary in medieval Latin records. Researchers working with English manor rolls, extent records, or early cadastral surveys should be alert to variant spellings and related forms. Because the corpus of law Latin boundary terms overlaps with terms rooted in "marca" (march, border region), there is potential for confusion between MARCHIARE as a verb of adjacency and terms denoting the March as an administrative or jurisdictional zone. These are related in origin but distinct in legal function.
Researchers using finding aids or indexes organized by modern English glosses should note that MARCHIARE may be catalogued under "adjoin," "border," "abut," or simply left untranslated. Cross-referencing against Cowell's Interpreter — the source Burrill cites — is advisable when the precise geographic context of a record matters to the research question.
Historical Dictionary Support
Burrill's Law Dictionary provides the only entry in the Law Mind shelf, giving a concise gloss — "to adjoin, or border upon" — and citing Cowell as authority. The entry is minimal by design, as the term has a single, narrow application. No substantive divergence exists across sources, largely because the term does not appear to have generated legal dispute or doctrinal elaboration; it is descriptive vocabulary of medieval surveying and conveyancing practice rather than a term carrying legal consequence of its own.
What historical dictionaries collectively leave unaddressed is the broader family of related boundary terms in law Latin — ADJACERE, ATTINGERE, CONTINGUUM ESSE — which overlap in meaning and appear in similar documentary contexts. Researchers should treat Burrill's gloss as a starting point and consult a specialist law Latin glossary (such as Latham's Revised Medieval Latin Word-List) when precision is required for textual editing or translation work.
Jurisdictional Note
MARCHIARE is a term of medieval English legal Latin and is most likely to appear in records of English or Anglo-Norman provenance. Similar terminology exists in continental European land records, but the specific word form and its documentary context are characteristic of the English tradition.
