Definition
A Latin term from old English law meaning noon — specifically, the middle of the day, midday. It appears in medieval legal instruments, court records, and procedural texts as a temporal marker designating when an act was performed, when a court sat, or when a deadline expired. The term carries no doctrinal weight of its own; its significance is entirely chronological and procedural, fixing a moment in the legal day.
Common Language
Modern common usage (Wiktionary): Meridies is the Latin word for midday or noon, the point at which the sun reaches its highest position. It survives in common English derivatives such as "meridian," "ante meridiem" (a.m.), and "post meridiem" (p.m.).
Historical common usage (Webster's 1913): The term does not appear as a standalone English entry in Webster's 1913, reflecting its status as a learned or technical Latin borrowing rather than a naturalized English word.
The gap between common and legal usage here is narrow but worth noting: in common contexts, meridies simply marks a moment in astronomical or clock time. In old English legal usage, noon had procedural and jurisdictional significance — courts observed specific hours for sitting, and time-of-day designations in instruments and writs were not merely descriptive but legally operative.
Why It Matters in Research
Researchers encountering meridies in historical legal materials should treat it as a procedural timestamp rather than a term of art with substantive meaning. Its significance lies in the document it appears in, not in the term itself.
Several research traps are worth flagging. First, meridies appears almost exclusively in medieval and early modern English sources — it is essentially absent from post-seventeenth-century legal writing. A researcher working in Year Books, Bracton, Fleta, or similar early English authorities will encounter it; a researcher in nineteenth-century or later materials almost certainly will not. Second, the related time-markers ante meridiem and post meridiem remain in active legal and evidentiary use (in affidavits, timestamps, court filings), but these phrases are treated as common Latin abbreviations rather than legal terms. Researchers should not assume that the procedural significance medieval law attached to the hour of noon carries forward into those modern usages. Third, the medieval legal day was organized differently from the modern clock day. "Noon" in a thirteenth-century English legal text may reflect canonical hours and ecclesiastical timekeeping as much as solar measurement. Context — the type of court, the nature of the proceeding, the century — determines what meridies actually fixed.
Within the Law Mind corpus, meridies connects most naturally to research on temporal elements of writs and pleadings, the law of process and return of writs, and the procedural framework of old English courts. Fleta (lib. 5, c. 5, § 31), the source cited by all three historical dictionaries, is the anchor reference for this term.
Historical Dictionary Support
The three historical dictionaries that include this term are in full agreement: meridies means noon, and it belongs to old English law. Black's (1st Ed.), Black's (2nd Ed.), and Burrill's each define the term in a single sentence and cite the same passage from Fleta. There is no divergence among sources and no evolution of meaning to trace — this is a frozen term, meaningful only within the medieval common law world from which Fleta emerged.
Burrill's entry is marginally richer, noting that the term is "L. Lat." (Law Latin) rather than classical Latin, a distinction that matters for corpus researchers: Law Latin is a specialized technical register, and meridies in legal texts should be read against that register rather than against classical or ecclesiastical Latin sources. Burrill also clusters meridies alongside MERISME and MERESME (Law French terms for timber), which are entries immediately following it alphabetically — an incidental reminder that Law Mind researchers working in this region of the historical dictionaries will encounter a dense mix of Law Latin and Law French terms from roughly the same medieval English period.
No historical dictionary offers analysis of how meridies functioned procedurally, what consequences attached to an act performed at or after noon, or how courts understood the term in disputed timing cases. That analysis must be sought in the primary sources, particularly Fleta and the Year Books.
