Definition
An obsolete Law French verb meaning "to escape." Used in early English legal texts to describe the act of a prisoner breaking free from lawful custody. The term appears in medieval pleading and statutory language to describe the fact of escape itself — the physical departure of a prisoner from the control of a jailer or other custodian.

Common Language
Modern common usage (Wiktionary): "Escape" — to break free from confinement or danger; to get away from a pursuer or threatening situation.
Historical common usage (Webster's 1913): "Escape" — to flee from and avoid danger or evil; to get out of the way of harm.
The common and legal meanings here are closely aligned in substance, but the gap lies in register and function. In ordinary English, "escape" is a general verb. In medieval legal practice, *eschaper* was a term of art embedded in pleading formulas and custodial accountability rules — its appearance in a document signaled specific legal consequences for the jailer, not merely a description of movement.

Common Confusion
ESCHAPER should not be confused with the noun forms ESCAPE (the act or offense) or ESCAPEE (the person who has fled). As a verb form in Law French, *eschaper* denotes the action itself and was used in documentary and pleading contexts rather than as a charge or cause of action by name. Researchers may also encounter NEGLIGENT ESCAPE and VOLUNTARY ESCAPE as distinct legal categories — concepts that developed in substantive English law well after the Law French vocabulary was in common use.

Why It Matters in Research
This term is essentially a philological marker. Encountering *eschaper* in a source almost certainly places the document in the Anglo-Norman legal tradition — early English Year Books, Britton, Bracton-era texts, or materials drawing directly on those sources. It will not appear in modern case law or statutes.
The primary research value is navigational: if a researcher is working through early English legal manuscripts or secondary sources quoting medieval custodial law, recognizing *eschaper* as a Law French verbal form for "escape" prevents misreading or false searches. A researcher who does not recognize the term as Law French might mistakenly treat it as a proper noun or a term of art with independent legal content.
The passage in Burrill — drawn from Britton, a late-thirteenth-century treatise on English law — illustrates how custodial escape was framed as a factual predicate in the legal text: the condition of having escaped was stated in the Law French form before consequences were addressed. Britton chapters 11 and 21 treat the duties and liabilities of those responsible for prisoners, and *eschaper* appears in that doctrinal context.
Researchers tracing the history of escape as a criminal offense or the civil liability of jailers for escapes should treat *eschaper* as a starting point in the earliest stratum of sources, with the understanding that the doctrinal architecture built around the concept develops substantially in later common law materials under the English term "escape."

Historical Dictionary Support
Burrill's Law Dictionary provides the sole historical dictionary entry for this term, offering a direct translation ("to escape") and a quotation from Britton. The entry is brief and purely definitional, which is appropriate: *eschaper* carries no specialized legal meaning beyond its plain verbal sense; its significance is in its appearance in authoritative early texts rather than in any technical content of its own.
No other historical dictionaries in the Law Mind corpus — including Jacob's Law Dictionary, Bouvier's, or Black's early editions — carry a separate entry for *eschaper* as distinct from the noun "escape," which reflects the term's status as a linguistic artifact rather than a living legal concept. The substantive law of escape, including the distinction between negligent and voluntary escape, and the liability of sheriffs and jailers, is developed in those later dictionaries under ESCAPE rather than under the Law French form.
