Definition
In medieval European law, to warrant; to give or furnish a warranty. The term appears in Latin legal instruments and records of the feudal period, principally on the Continent, where it denoted the act by which a grantor or lord undertook to guarantee title or peaceful possession of land to a grantee or tenant. The obligation to warentare was the operative verb-form underlying the feudal duty of warranty — the formal commitment to defend and secure the conveyance against adverse claims.
Why It Matters in Research
WARENTARE is a term a researcher will encounter only in medieval Latin documents — charters, cartularies, feudal registers, and the comparative legal scholarship that draws on Lombard and early Continental sources. Several navigation points deserve attention.
First, the term's primary context is old European (especially Lombard) law, not English common law. A researcher working in English Year Books or Plea Rolls should look instead to WARRANTIA DEDI or the warranty clauses of English conveyancing. WARENTARE signals Continental, not insular, provenance.
Second, the verbal form is significant. Warranty scholarship tends to focus on the noun forms — warrantia, garantia — and the clause "et ego warantizabo." WARENTARE as an infinitive signals that a researcher is likely in a formulaic clause within a grant or charter, not a standalone legal instrument. Recognizing the verbal context helps locate the document type quickly.
Third, the Lombard derivation (guarentare) is directly relevant to comparative legal history research. Scholars tracing the development of warranty doctrine from Germanic custom through Lombard law into the ius commune and ultimately into English feudal practice will find WARENTARE a useful linguistic marker connecting those traditions. The term's appearance in a source is therefore not merely definitional — it is a historiographical signal about the legal culture producing the document.
Finally, because WARENTARE appears in Latinized form in sources compiled from Lombard originals, transcription variation is a real research hazard. Spellings including garantare, warantare, and guarantare may appear interchangeably in edited collections and indices. Search strategies in digitized corpora must account for these variants.
Historical Dictionary Support
Burrill's Law Dictionary provides the entry in full: "L. Lat. [Lomb. guarentare.] In old European law. To warrant. Spelman." The entry is minimal even by the standards of Burrill's handling of Latin feudal terms, offering a definition of a single word and directing the reader to Spelman — meaning Sir Henry Spelman's Glossarium Archaiologicum, the standard seventeenth-century reference for archaic and medieval legal Latin. Burrill adds nothing beyond the Lombard root and the Spelman attribution.
The entry's brevity reflects the term's narrow functional role: WARENTARE was an operative term of art whose meaning was entirely captured by its English equivalent (to warrant) and whose significance lay in context rather than in any complex doctrinal content of its own. Historical dictionaries generally treat warrant-family terms expansively at the noun level (WARRANTY, WARRANTIA) but lightly at the verb level, which is consistent with Burrill's approach here.
No other Law Mind shelf sources treat WARENTARE as a discrete entry, though the underlying concept of warranty appears across Bouvier, Black, and the common law treatise tradition at considerable length under WARRANTY and its cognates.
