Definition
In old English and medieval Latin legal usage, *strata* (also *stratae*) referred to a street or road. The term appears in two principal forms in historical English legal sources:
1. *Strata regalis* — the king's highway; a royal road over which the Crown exercised jurisdiction and protection.
2. *Stratae publicae* — public streets or ways open to common use.
Burrill notes that *strata* properly denotes a paved way (from the Latin *sternere*, to lay or spread), but cautions that it was not used in that strict sense in English legal sources. The term functioned as a general designation for roads and streets in medieval pleading, writs, and legal treatises, without requiring that the way be physically paved.

Common Language
Modern common usage (Wiktionary): Plural of *stratum*; layers or levels, especially of rock, soil, or society.
Historical common usage (Webster's 1913): Plural of *stratum*; horizontal layers of material, particularly geological deposits.
The gap here is significant. To a modern reader — or even a nineteenth-century one — *strata* means layers, typically geological or sociological. In historical English legal Latin, it meant roads or streets, drawing on a wholly different sense of the same Latin root. A researcher encountering *strata* or *stratae* in a medieval writ or Bracton passage should not import the modern geological meaning; the legal usage is a false cognate in practice.

Why It Matters in Research
Researchers working in medieval English law, early common law pleading, or the history of highway law will encounter *strata*, *strata regalis*, and *stratae publicae* as technical terms in sources written in Law Latin. The risk of misreading is real: the modern English meaning of *strata* (geological or social layers) will mislead a reader who does not recognize the highway-law context.
The term is most likely to appear in:
- Bracton's *De Legibus et Consuetudinibus Angliae* (Bract. fol. 170b), where *stratae publicae* appears in discussions of public ways and their protections.
- Fleta (lib. 2, c. 49, § 11), which uses *strata regalis* in the context of royal highway jurisdiction.
- Old writs and pleadings involving obstruction of roads, nuisance on highways, or royal road maintenance obligations.
The distinction between *strata regalis* (the king's highway, with its distinct legal protections and Crown jurisdiction) and *stratae publicae* (public streets more generally) mattered in practice: interference with a *strata regalis* carried heightened legal consequences. Researchers tracing the history of highway law, royal prerogative over roads, or the development of public nuisance doctrine should treat these as terms of art with jurisdictional and hierarchical significance.
The 10 Modern Reports citation (10 Mod. 382) flagged by Burrill signals that early eighteenth-century English courts were still clarifying the scope of the term, confirming that *strata* remained a live concept in common law highway cases well beyond the medieval period.

Historical Dictionary Support
Burrill's Law Dictionary provides the core entry, tracing *strata* and its compounds to Bracton and Fleta — the foundational authorities of medieval English law. Burrill is careful to note both the etymological meaning (paved way) and the actual legal usage (roads and streets generally, without a paving requirement), which is a meaningful distinction for interpreting historical sources literally versus legally.
No other shelf dictionaries in the present corpus cover *strata* as a legal term. Researchers should treat Burrill's entry as the primary reference and consult Bracton and Fleta directly for context. Later English legal dictionaries and glossaries of Law Latin (such as Du Cange's *Glossarium* for the medieval Latin tradition) would provide additional depth for the term's continental usage, but those fall outside the present corpus.

Jurisdictional Note
*Strata* as a legal term of art is specific to English legal Latin and the common law tradition derived from it. Civil law jurisdictions used different terminology for roads and public ways. Researchers working in Scottish, Irish, or American colonial sources should verify whether the term appears in direct transplantation from English sources or simply as a Latin plural of *stratum* in a geological or descriptive sense.
