Definition
A Latin legal term from old English law denoting a tannery — the physical place of business where hides are processed into leather — or more broadly, the trade or occupation of a tanner. The term appears in medieval legal instruments and treatises as a descriptor of a specific lawful trade and the premises associated with it.
Why It Matters in Research
TANNERIA is an archaic Law Latin term encountered almost exclusively in medieval English legal records, pleadings involving trade regulation, and property descriptions. Researchers consulting early common law sources — particularly manuscripts and commentaries drawing on Fleta — may encounter the term when tracing the legal status of particular crafts and the premises associated with them. In medieval English law, specific trades carried specific legal incidents: licensing, nuisance liability, and regulatory obligations attached to the tanneria as both a place and a business category.
The term is essentially extinct in modern legal usage. A researcher encountering it in a historical document should treat it as a property or trade descriptor, not a term of art with ongoing doctrinal significance. It is most relevant in two research contexts: (1) historical real property records where a tannery is identified as a subject of conveyance, lease, or devise; and (2) medieval trade regulation and guild law, where the tanneria appears as a recognized occupational category subject to crown or municipal oversight.
Note that the second edition of Black's Law Dictionary contains a stray entry — TALLEY or TALLY — appearing in the source material immediately adjacent to TANNERIA. This is a pagination or compilation artifact, not a related term. Researchers working from digitized or compiled historical dictionary sources should be alert to such cross-contamination between adjacent entries.
Historical Dictionary Support
The source dictionaries are in precise agreement on TANNERIA: it means tannery or the trade of a tanner, rooted in old English law. Black's Law Dictionary (1st Ed.) and Burrill's Law Dictionary both cite Fleta, lib. 2, c. 52, § 35 as the authoritative source — a 13th-century legal treatise compiled during the reign of Edward I, understood to draw heavily on Bracton. Rapalje & Lawrence echo the same definition without the Fleta citation but append the neighboring maxim "Tantum bona valent, quantum vendi possunt" — a reminder that in historical dictionary formats, entries were often compressed and proximately placed with unrelated material, requiring careful reading.
None of the source dictionaries expand meaningfully on the legal incidents of a tanneria — its regulatory context, how it was treated in conveyancing, or what nuisance doctrines attached to it. Researchers needing that depth must go to Fleta directly or to secondary scholarship on medieval English trade law. The dictionaries function here as identification aids, not analytical sources.
Jurisdictional Note
TANNERIA is a term of old English law with no equivalent in American legal usage. It does not appear in U.S. statutory or common law as a term of art. Researchers encountering it in American historical documents are likely reading instruments drafted under English legal forms or by practitioners trained in English legal conventions.
