Definition
An archaic Latin term appearing in old English records, meaning the profit or product of ground — that is, the yield or revenue derived from land. The term reflects the medieval legal conception of land value expressed through its productive output rather than its capital worth.
Why It Matters in Research
INBLAURA is a term researchers will encounter almost exclusively in transcribed or translated medieval English records — manorial accounts, conveyancing documents, and early chancery materials — rather than in any living body of doctrine. Its significance is terminological: when a historical source refers to inblaura, it is describing the fruits of land (crops, revenues, produce) rather than the land itself or any legal interest in it. Researchers examining property disputes, tithes, or manorial obligations in pre-modern sources should treat inblaura as an economic descriptor, not a term of legal art defining a right or action. Conflating it with terms of legal entitlement would distort the source's meaning.
Note also that the second edition of Black's Law Dictionary appended to the INBLAURA entry a separate and unrelated definition of INBOARD, a maritime law term concerning cargo stowage. Researchers consulting that edition should be alert to this typographical adjacency — the entries are distinct, and the maritime content has no connection to INBLAURA.
Historical Dictionary Support
All five source dictionaries agree on the core meaning: profit or product of ground. Each traces the definition to Cowell — that is, John Cowell's Interpreter (1607), the early glossary of law terms that served as the primary reference for obscure Latin and Saxon legal vocabulary through the eighteenth and nineteenth centuries. The uniformity here is notable: no dictionary adds doctrinal content, no dictionary records a case in which inblaura was at issue, and none extends the definition beyond Cowell's gloss. This unanimity signals that by the time these dictionaries were compiled, inblaura had no active presence in legal practice or litigation — it survived in the dictionaries as a scholarly entry rather than a working term.
Burrill's Law Dictionary situates INBLAURA directly alongside INBORH (a Saxon pledge or security for persons), which underscores that these are discrete entries sharing only alphabetical proximity. Rapalje & Lawrence similarly follow the INBLAURA entry with INBORH without conflating the two. Researchers should not infer any substantive relationship between these terms.
Jurisdictional Note
INBLAURA is confined to the historical record of English law. It carries no recognized meaning in American, Scottish, or other common law jurisdictions, and does not appear in any modern statutory or regulatory context.
