Definition
A Law French term meaning "by night." Used in early English legal records and year books to describe acts, offenses, or circumstances occurring during the nighttime hours. The term appears in medieval pleading and reporting as a temporal qualifier, distinguishing conduct that took place after dark from daytime conduct — a distinction that carried legal significance in a range of contexts, including burglary, trespass, and certain procedural matters.

Why It Matters in Research
Researchers encountering NOCTANDRE in primary sources are almost certainly working with Year Book materials or early common law pleadings predating the consolidation of English legal language. The term is a marker of Law French, the hybrid legal dialect used in English courts from the Norman Conquest through the seventeenth century. Its presence signals that the surrounding text is likely from medieval or early modern records where terminology has no direct modern statutory counterpart.
The practical significance of "by night" as a legal qualifier is not merely atmospheric. In the historical common law, nighttime was a formal element of certain offenses — most notably burglary, which required breaking and entering a dwelling house in the nighttime. The distinction between nocturnal and diurnal conduct could determine whether an act constituted a felony or a lesser offense. Researchers tracing the development of burglary doctrine, nighttime trespass, or curfew-related offenses may encounter NOCTANDRE in source materials as a direct ancestor of the "nighttime" element that persisted in statutory definitions well into the modern era.
Because the term appears primarily in Year Book citations, researchers should be alert to the limitations of Year Book transcription and translation. Year Books were not official reports; they were law student and practitioner notes, often inconsistent in spelling and usage. NOCTANDRE may appear in variant spellings across different manuscript traditions. Do not assume uniform usage across sources.
The term itself has no active role in modern legal language and will not appear in contemporary statutes, regulations, or case law. Its research value is exclusively historical and linguistic — as evidence of how temporal distinctions were pleaded and recorded in early English courts.

Historical Dictionary Support
Burrill's Law Dictionary provides the sole entry among the shelf sources, defining NOCTANDRE concisely as the Law French equivalent of "by night" and citing Yearb. M. 5 Edw. III. 31 as authority. The citation refers to a Michaelmas term Year Book entry from the fifth year of the reign of Edward III, placing the term's documented use in the early fourteenth century (circa 1331–1332).
Burrill offers no further elaboration beyond the citation, which is characteristic of how Law French terms of purely linguistic function were treated in nineteenth-century legal dictionaries — identified, translated, sourced, and left to the researcher to contextualize. No other shelf sources include an independent entry for NOCTANDRE, which reflects both the term's narrow usage and its obsolescence by the time modern legal dictionaries were compiled.
The absence of this term from later dictionaries such as Black's should not be read as evidence that the concept disappeared — the nighttime element in criminal law remained vital — but rather that the Law French vocabulary was shed as English displaced French in legal proceedings and reporting.
