Definition
An archaic Law French term meaning "to beware" or "to be on guard." It appears in early legal texts as a warning or cautionary instruction, most often embedded in procedural or evidentiary passages directing a party or judge to take notice of something that might otherwise escape detection. The term is not a standalone legal concept with operative legal effect but functions as a signaling word within Law French legal discourse, alerting the reader to a condition or circumstance requiring particular attention.

Common Confusion
ENCAVER should not be confused with the adjacent terms appearing in Burrill's compressed alphabetical sequence. ENCEA or ENCI (meaning "so" or "also" or "afterwards") and ENCEINT/ENCEINTE (meaning pregnant or with child, a term with significant procedural consequence in early criminal law regarding execution of female defendants) are entirely distinct in meaning and legal function. The physical proximity of these headwords in Burrill's dictionary and the fragmented presentation of the entries creates a real risk of misreading or conflation, particularly when working from older or poorly digitized editions.

Why It Matters in Research
ENCAVER is the kind of term that will stop a researcher cold in a transcribed or printed Law French source. It carries no continuing legal meaning in modern practice and will not appear in contemporary statutes, regulations, or case law. Its significance is entirely historical and textual.
Researchers working with early English legal manuscripts, Britt on (Britton), Kelham's Interpreter of Norman and Ancient French, or other Law French materials will encounter this term as part of the ambient vocabulary of cautionary and procedural language — a category of words that served as rhetorical flagging devices rather than terms of art with defined legal consequences.
The fragment preserved in Burrill is instructive. The passage concerns an increase (encres) so imperceptible (soutil) that no one could see or perceive it as it accrued over time. The word encaver appears in context as the warning embedded in that observation — essentially, "beware" the situation where an accumulation or change has occurred so gradually as to be invisible to ordinary scrutiny. This context has relevance to research on adverse possession, prescription, and the gradual accrual of rights or encumbrances in early English property law, where the imperceptibility of change was legally significant to questions of notice and laches.
A trap for researchers: Burrill's entry is fragmented and runs together with adjacent Law French headwords (ENCEA, ENCI, ENCEINT), reflecting the compressed and sometimes chaotic alphabetical arrangement common to early legal dictionaries. Do not assume the passage quoted under ENCAVER represents a complete sentence or a self-contained legal rule — it is an excerpt, and its full context must be sought in the primary sources Burrill cites, particularly Kelham.

Historical Dictionary Support
Burrill's Law Dictionary is the sole historical dictionary source providing coverage of this term, and its entry is notably truncated. The definition given is simply "to beware," with the illustrative passage only partially reproduced. The excerpt references a scenario of imperceptible increase — an encres so subtle that neither sight nor perception could detect its accumulation over time (par proces de temps). The primary authority Burrill points toward is Kelham's French-English legal glossary, which remains one of the more reliable guides to Law French vocabulary of the Norman and early common law periods.
No coverage of ENCAVER appears in standard modern legal dictionaries, Black's Law Dictionary across its editions, or Bouvier's Law Dictionary. This absence confirms the term's status as a historical artifact of Law French usage rather than a living term of art. Researchers should treat it as vocabulary archaeology — useful for understanding the rhetorical and procedural register of early legal texts, not as a concept with doctrinal significance to trace forward.

Jurisdictional Note
ENCAVER is a term of Law French, the legal language of Norman and early English common law. It has no recognized meaning in any American, Canadian, or post-Norman-period jurisdiction. Its relevance is confined to research in English legal history predating the gradual displacement of Law French from the courts, a process largely complete by the late seventeenth century.
