Definition
An obsolete term from medieval Latin used in old English records to denote a vessel of lading or burden — that is, a cargo-carrying watercraft. The term refers specifically to a small seagoing or coastal transport ship used for the conveyance of goods, comparable in function and size to what was historically called a hoy or smack. It appears in administrative and patent records of the late medieval period and belongs to the vocabulary of early maritime and commercial law.
Why It Matters in Research
Craiera is a narrow archaic term encountered almost exclusively in medieval English administrative records, particularly patent rolls and similar crown documents. Researchers working in early maritime law, medieval trade regulation, or the history of English commercial practice may encounter the term in transcribed or original Latin records and require identification before the surrounding legal context makes sense.
The term is effectively a technical descriptor rather than a legal concept — it names a type of vessel rather than establishing a right, duty, or cause of action. This means it will not appear in doctrinal legal literature or in case law beyond incidental reference. Its value to the researcher is primarily identificatory: recognizing craiera as a cargo vessel prevents misreading of a document's subject matter and helps establish what kind of commercial or admiralty transaction is being recorded.
Researchers should also note that the related form crayer (or crare) appears in some sources as an Anglicized variant. Burrill himself cross-references Crayer, indicating the two entries describe the same vessel type under slightly different spellings. When searching historical indexes or digitized record collections, both spellings — and potentially craiere, creyer, or crayer — should be tried, as medieval Latin and Law Latin orthography was not standardized.
Historical Dictionary Support
Burrill's Law Dictionary provides the sole substantive entry among the available shelf sources. Burrill defines craiera as a vessel of lading or burden, equates it with a hoy or smack, and anchors the term to a specific record: Pat. 2 Ric. II — that is, a patent roll from the second year of Richard II's reign (1378–1379). The authority he cites for the definition is Cowell, referring to John Cowell's Interpreter (1607), one of the foundational early modern glossaries of Law Latin and legal terminology.
The entry is brief but precise. Its value lies primarily in the patent roll citation, which gives researchers a documentary anchor for the term in English administrative practice. The reference to Cowell situates the term within the early glossarial tradition that sought to decode the Law Latin of medieval English records for contemporary (seventeenth-century) practitioners.
No broader doctrinal elaboration exists in the available sources because craiera never developed into a legally operative concept — it was always a descriptive term for a class of vessel rather than a term of art carrying legal consequences.
