Definition
An archaic legal term denoting a breach of law, and, by extension, the monetary penalty (mulct) imposed for such a breach — specifically fixed at twelve "ores," a unit of account used in early medieval English and Scandinavian legal custom. The term appears in historical English legal records as both the name of the offense (the unlawful act itself) and the standardized fine attached to it.
Common Confusion
LAHLSLIT and LAHMAN are adjacent entries in both Black's editions and are easily conflated when the text is read quickly or in degraded scan quality. They are unrelated in meaning: LAHLSLIT is a breach of law and its associated penalty; LAHMAN (Lagemannus) is a person — a lawyer or lawman — recognized in Domesday Book. A researcher searching for one term should confirm which entry they are actually reading.
Why It Matters in Research
LAHLSLIT is a term of purely antiquarian significance. No modern legal system uses it, and it carries no operative force in contemporary doctrine. Researchers will encounter it only when working in early medieval English legal history, Anglo-Scandinavian customary law, or the record literature of the Danelaw period.
The critical navigational point: Black's entries for LAHLSLIT bleed immediately into LAHMAN (or LAGEMANNUS), an old word for a lawyer appearing in Domesday Book (I. 189). Both terms share an entry block in the historical dictionaries, and a careless reader may conflate them. They are distinct: LAHLSLIT is the offense and fine; LAHMAN is the office or person. Researchers consulting microfilm or digitized scans of Domesday Book should be aware that early transcriptions vary the spelling of both terms considerably.
The "twelve ores" penalty is characteristic of Danelaw legal custom. An "ore" (or "ora") was a unit of account — typically sixteen pennies in the English Danelaw context, though the precise value varied by region and period. Any research into the fine's monetary significance requires consulting secondary scholarship on Anglo-Scandinavian numismatics and customary law rather than the dictionary entries alone, which give no further detail.
Cowell's Interpreter (1607), cited by Black's as the proximate source, is the standard early modern English legal glossary for obsolete terms of this type. When Black's cites "Cowell" without further specification, it means John Cowell's The Interpreter. Researchers should verify Cowell's entry directly, as Black's occasionally abbreviates or paraphrases his definitions in ways that flatten historical nuance.
Historical Dictionary Support
Both the first and second editions of Black's Law Dictionary give nearly identical entries, differing only in a minor spelling variation: LAGEMANNUS (1st ed.) versus LAGGEMANNDUS (2nd ed.) in the appended LAHMAN entry. Neither edition expands on the definition beyond Cowell's authority and the Domesday citation. This consistency across editions reflects that Black's had no independent research basis for the term — it passed Cowell's gloss forward without elaboration.
No other standard historical legal dictionary in the Law Mind corpus (Bouvier, Tomlin's Law Dictionary, Jacob's Law Dictionary) appears to carry a substantive independent entry for LAHLSLIT. The term's obscurity means that Black's reliance on Cowell is effectively the entire dictionary tradition for this word. Researchers requiring depth must go directly to primary sources: Domesday Book itself, Anglo-Saxon legal codes, and modern scholarly treatments of Danelaw law such as Patrick Wormald's work on early English law-making.
