Definition
A historical unit of measure for corn or grain, equal to twenty-four sheaves, arranged as four shocks of six sheaves each. Thrave appears in old English law primarily in the context of agricultural renders, tithes, and customary dues owed by tenants — situations where the precise quantity of grain delivered or owed required a standard unit of reckoning.
Common Language
Modern common usage (Wiktionary): To urge, compel, or importune.
Historical common usage (Webster's 1913): Twenty-four (in some places, twelve) sheaves of wheat; a shock or stook. Also used loosely to mean a company, a bunch, or an indefinite number. The verb sense ("to urge") is marked obsolete.
The legal meaning belongs entirely to the measuring-unit sense, not the verbal sense recorded in Wiktionary. The Webster's entry also flags a regionally variable count — twelve sheaves in some locales versus twenty-four in others — a discrepancy the legal dictionaries resolve by fixing the quantity at twenty-four. Researchers relying on non-legal sources should be alert to this variation when interpreting historical documents.
Why It Matters in Research
Thrave is a term of art in medieval and early modern English agricultural law. It surfaces most often in records involving grain tithes, customary tenure obligations, and manorial accounts, where renders in kind were stated by unit rather than by weight or price. The fixed legal definition of twenty-four sheaves matters because disputes over the quantity owed could turn on whether the local custom matched the legal standard.
The principal research trap is the variable count. Webster's 1913 records both twelve and twenty-four sheaves as historically attested, reflecting genuine regional divergence in English practice. When reading primary sources — manorial rolls, tithe accounts, customary surveys — the researcher should not assume the legal dictionary's twenty-four-sheave standard controlled locally. The document itself, or its regional context, may govern.
Thrave also appears in older statutes and ecclesiastical records concerning tithes in grain. Because the term is archaic and specific to agricultural renders, it drops out of legal usage entirely once payments in kind give way to money rents and commuted tithes. Researchers in post-enclosure or post-Tithe Commutation Act (1836) materials are unlikely to encounter it as a live legal term.
No modern American legal usage exists. The term is relevant only to researchers working in English legal history, medieval land law, ecclesiastical property, or the history of customary tenure.
Historical Dictionary Support
Both editions of Black's are in complete agreement, reproducing the same definition verbatim with only minor typographical differences. Both cite Cowell — John Cowell's Interpreter (1607), one of the foundational early modern English legal dictionaries — as the authority, which explains the consistency and also places the outer limit of independent verification: both Black's entries are derivative of the same single source.
Neither edition engages with the regional variability documented in Webster's 1913 or with the possibility that local custom might fix the thrave at twelve rather than twenty-four sheaves. For legal research purposes the Black's standard of twenty-four sheaves should be treated as the default, but Cowell's authority is early modern, and researchers working in truly medieval sources should consult specialized historical glossaries of agrarian terminology — such as those found in the works of Maitland or in the glossaries appended to editions of manorial records published by the Selden Society — for broader coverage.
Jurisdictional Note
Thrave is an English legal term with no recognized counterpart in American, Scottish, or other common law jurisdictions. It belongs to the specific context of English manorial and ecclesiastical law and is effectively obsolete even within English law following the commutation of tithes and the decline of customary agricultural tenure.
