Definition
To pledge; to give or offer something as security for the performance of an obligation or the payment of a debt. Wadiare is a Latin term drawn from medieval European legal usage, functioning as a verb form of wadium (a pledge). In practice, the act of wadiaring was the formal giving of a gage or pledge — a material object or surety — as security in legal proceedings or transactions.
The related noun form, WADIUS or WADIUM, refers to the pledge itself: the thing given or tendered as security.
Why It Matters in Research
Researchers working in medieval European legal sources — particularly records from Germanic, Norman, or early English legal traditions — will encounter wadiare and wadium in contexts that parallel the later common law concepts of gage, pledge, and mortgage. The term belongs to the stratum of Latin-rendered customary law that bridged Germanic folk law and Roman legal vocabulary, and it appears primarily in sources predating the systematization of English common law.
The key navigational point is that wadiare is almost never encountered in English case law or statutes directly; it surfaces in legal-historical treatises, glossaries of medieval law, and antiquarian legal scholarship. Spelman's Glossarium Archaeologicum is the primary authority to which Burrill refers, and researchers tracing this term will need to engage that source directly. It is also cognate with terms in early continental sources — Old French gage, and terms in Lombard and Frankish law — making comparative legal history the more natural research context than domestic case research.
If you encounter wadiare in a primary source, read it as functionally equivalent to an act of pledging security, but be attentive to the specific procedural context: in some medieval usages, wadiare referred to the formal tender of a pledge in a judicial proceeding (analogous to waging law or waging battle), not merely a private contractual security transaction.
Historical Dictionary Support
Burrill's Law Dictionary gives the entry in compressed form, defining wadiare simply as "to pledge" and citing Spelman. The noun forms wadius and wadium are defined as "a pledge." Burrill adds no expansion beyond the Spelman citation, which reflects the term's narrow relevance to antiquarian legal research rather than to the active common law practice of Burrill's own period.
No other Law Mind shelf source addresses this term directly. Burrill's restraint here is appropriate: this is a term of historical record rather than of living legal doctrine. Researchers should treat Burrill as a pointer to Spelman rather than as a self-contained authority on this term.
