Definition
Leis is an archaic legal term, appearing in early English legal records, meaning galleys — specifically, oared vessels used for naval or maritime purposes. The term appears in Latin or Law French legal texts and glossaries, typically in the context of naval levies, maritime service obligations, or the equipment required of certain landholders under feudal tenure.
The word is essentially a relic of medieval administrative and legal writing and has no operative meaning in modern law.
Common Language
Modern common usage (Wiktionary): Plural of lei — the Hawaiian floral garland or, in finance, the plural of leu, the Romanian currency.
Historical common usage (Webster's 1913): Not separately defined; no relevant entry.
Editorial note: The legal term leis has no connection to the modern common uses of the word. A researcher encountering leis in a contemporary context is almost certainly not dealing with a legal term. The legal meaning is strictly confined to medieval Latin and Law French source documents.
Why It Matters in Research
The principal research risk with leis is misidentification. A researcher working in digitized medieval English records, feudal tenure documents, or early maritime law sources may encounter the term in contexts involving naval service obligations or ship-levies. Without knowledge of this meaning, the term could be misread or passed over entirely.
The term appears in specialist glossaries — notably Spelman's Glossary (Spel. Gloss.) and Kelham's dictionary of Norman French legal terms — rather than in mainstream legal dictionaries. This signals that its primary utility is as an aid to reading primary sources, not as a working legal concept. Researchers dealing with Anglo-Norman or Latin administrative records should have access to both Spelman and Kelham when leis or related terms appear.
No modern statutory or case law use is expected. If leis appears in any post-medieval legal document, it is almost certainly a quotation, transcription, or historical reference rather than operative legal language.
Historical Dictionary Support
Bouvier's entry is minimal: "A galley, galleys. Spel. Gloss.; Kelham." This is a straightforward cross-reference entry, indicating that Bouvier himself drew the term from earlier specialist glossaries rather than from active legal usage in his own era. The brevity confirms that by the nineteenth century, leis was already understood as a purely historical term requiring external authority for its definition.
Spelman's Glossarium Archaeologicum and Kelham's Dictionary of the Norman or Old French Language are the foundational sources here. Bouvier defers entirely to them, and any researcher needing fuller context for leis in a specific document should consult those works directly.
No significant divergence among historical sources is present because the historical record is thin. There is agreement on the basic meaning — galleys or oared vessels — but no elaboration on the specific legal contexts in which the obligation or reference to leis arose.
