Definition
An archaic Law French term meaning "to hurt" or "to injure." Encountered in historical legal texts in its conjugated forms: *ledera* (shall hurt) and *ledez* (hurt). The term appears in early English legal records written in Law French, the hybrid legal language used in English courts from the Norman Conquest through the seventeenth century.
Common Language
Modern common usage (Wiktionary): No current entry. The term is obsolete in both common and legal English.
Historical common usage (Webster's 1913): Not listed. By the nineteenth century the term had passed entirely out of use.
Editorial note: *Leder* has no meaningful counterpart in modern English. It belongs exclusively to the Law French stratum of legal vocabulary and should be treated as a specialist paleographic term rather than a word with any surviving legal or common meaning.
Common Confusion
*Leder* should not be confused with the modern English word "leader" or the German/Dutch word *Leder* (meaning leather). The superficial resemblance to these words is purely accidental. When encountered in a manuscript or early printed legal source, the context of injury, harm, or physical wrong is the reliable interpretive signal.
Why It Matters in Research
Researchers working with early English legal records — particularly plea rolls, year books, and other pre-modern court documents composed in Law French — may encounter *leder*, *ledera*, or *ledez* where a modern instrument would use terms like "injure," "assault," or "harm." Recognition of this vocabulary is essential to accurate reading of manuscript sources; misreading or skipping the term can cause a researcher to miss a substantive allegation of wrongful injury in a pleading or judgment.
The conjugated form *ledera* (shall hurt) suggests conditional or future-tense pleading constructions common in writs and in formulaic allegations of threatened harm. *Ledez* (hurt, past tense) appears in completed-act allegations. Distinguishing these forms matters when reconstructing what was actually alleged in an early proceeding.
Because Law French legal vocabulary was never fully systematized in the way Latin legal terminology was, variant spellings of this root are possible in manuscript sources. Researchers should not assume that the forms listed here are exhaustive.
Historical Dictionary Support
Burrill's Law Dictionary is the sole source among the major historical legal dictionaries to record this term, citing Kelham's *Dictionary of the Norman or Old French Language* (1779) as its authority. This attribution is significant: Kelham's work remains a primary reference for Law French legal vocabulary, and its identification of *leder* as deriving possibly from the Latin *lædere* (to hurt, to damage) places the term within a recognizable family of legal concepts centered on physical or civil injury.
No entry appears in Jacob's *Law Dictionary*, Tomlins, Bouvier, or Black's editions, confirming that the term was already a historical curiosity by the time the major nineteenth-century dictionaries were compiled. Burrill's inclusion of it reflects his broader commitment to preserving Law French and Latin terminology that had dropped from active use but remained essential to reading older sources accurately.
The possible Latin root *lædere* is worth noting for researchers: the same root underlies *laesio* (injury, harm), which survived in active legal use in both civil law and some common law contexts well into the modern period, particularly in the concept of *laesio enormis* (grossly disproportionate loss in a contract). *Leder* is thus a Law French vernacularization of a concept with a much longer Latin pedigree.
Jurisdictional Note
Relevant only to historical English common law jurisdiction. The term has no application in American law, Scottish law, or civilian legal systems, and will not appear in any source postdating the decline of Law French as a language of English legal pleading.
