Definition
A term of Anglo-Norman and Law French derivation, functioning as a verb of knowledge or notice in early English legal instruments and records. Sacher means "to know" or "know ye," drawn from the Old French savoir (itself from the Latin scire). It appears in formulaic legal phrases directing attention or conferring notice on readers or parties — functioning much as the Latin scire facias or the English "know all men" in later instruments.
The term is encountered almost exclusively in medieval and early modern legal documents written in Law French, including statutes, Year Books, and Britton's legal compilation. It does not survive as an operative term in modern legal practice.
Common Language
Modern common usage (Wiktionary): A German surname.
Historical common usage: Not recorded as an English common word in Webster's 1913; the term belongs to Old French, not English, vocabulary.
The gap is significant: researchers encountering sacher in a historical legal document should not read it as a proper name. In Law French legal texts, sacher is a verb commanding notice or knowledge, and its appearance in a phrase is functional, not nominal.
Common Confusion
Sacher is easily misread as a proper name by researchers unfamiliar with Law French legal formulae. The confusion is compounded because the word does not appear in standard French dictionaries of the modern period and is absent from most English legal glossaries that focus on Latin rather than Law French sources. It should be distinguished from the Latin scire (to know), with which it is functionally equivalent and historically connected, and from savoir, its direct Old French ancestor.
Why It Matters in Research
The primary research risk is misidentification. A researcher indexing or transcribing a Year Book entry or medieval statute who does not recognize sacher as a Law French verb will either mistake it for a proper noun or flag it as an unresolved term. Both errors corrupt transcriptions and search results.
In the Law Mind corpus, sacher will appear in:
— Britton, the late-thirteenth-century Anglo-Norman legal compilation, where phrases like et chescun sache son several direct that each party know their separate portion of a matter.
— Year Book entries, where the word anchors notice clauses.
— Statutory texts in Law French, such as the Statute of Confirmation of the Charters (Confirmatio Cartarum), where the opening formulae address readers with sachez or sachent touts.
Researchers should treat sacher and its inflected forms (sache, sachez, sachiez) as a single functional vocabulary cluster meaning "to know / let it be known." The phrase saches touts gens — "know all people" — is the Law French equivalent of the Latin noverint universi and the English "know all men by these presents," a formula still visible in modern bond instruments. Recognizing this genealogy helps researchers trace the continuity of notice-giving formulas across language and era within the corpus.
Historical Dictionary Support
Burrill's Law Dictionary is one of the few English legal dictionaries to document sacher explicitly, cross-referencing it to scire and noting its Latin derivation. Burrill quotes directly from the Statute of Confirmation of the Charters and from Britton, which grounds the entry in genuine primary sources rather than abstract etymology.
What Burrill does not provide is a full treatment of the inflectional variation — sache, sachez, sachiez — which appear across sources as mood and person shift. Researchers should not expect the lemma sacher to be the only form they encounter; the imperative and subjunctive forms are at least as common in formulaic legal language as the infinitive.
No other major historical law dictionary in the standard reference shelf (Bouvier, Black, Tomlin, Jacob) devotes a dedicated entry to sacher, reflecting a broader tendency to privilege Latin over Law French in legal lexicography. This gap makes Burrill's entry more valuable than its brevity suggests.
Jurisdictional Note
Sacher belongs to English legal history specifically, reflecting the Law French that dominated English legal practice from the Norman Conquest through the seventeenth century. It has no direct counterpart in Scottish, Irish, or continental civil law traditions. Researchers working in Welsh records or Channel Islands law may encounter related French-language formulas but should verify local usage independently.
