Definition
Limericensis comitatus is a Latin phrase meaning "the County of Limerick," referring to the historic county in Ireland. The term is a formal Latinized designation of the kind routinely used in legal and administrative documents composed in Law Latin — particularly pleadings, writs, patents, commissions, and official records — where place names were rendered in their classical or ecclesiastical Latin form rather than in the vernacular. Limerick (in Irish, Luimneach) appears in this form in instruments originating from or directed to English and later British colonial administration of Ireland.
The term has no substantive legal content of its own. It is a geographic identifier, functioning in legal instruments the same way a modern jurisdictional designation functions: to locate a matter, a party, a grant, or a proceeding within a specific county. Its significance to a researcher is almost entirely contextual and philological — knowing what it means and how to recognize it.

Why It Matters in Research
The practical challenge with Limericensis comitatus is recognition, not interpretation. Researchers working in pre-modern Irish legal records, English chancery documents, crown grants, or plantation-era instruments will encounter a dense vocabulary of Latinized place names. Failure to recognize Limericensis as "Limerick" can derail a search, cause misidentification of a document's geographic scope, or obscure the connection between related records filed under different name forms.
Several specific traps apply:
First, the adjective form (Limericensis) will appear in multiple grammatical cases depending on its function in a sentence — Limericensis, Limericensi, Limericensem, and so on. Researchers unfamiliar with Latin declension may not recognize all forms as referring to the same county.
Second, Limerick appears in records under at least three naming conventions: the Latinized form (Limericensis comitatus or comitatus Limericensis), an Anglicized Latin hybrid (Comitatus Limerick), and the plain vernacular English (County Limerick or the County of Limerick). A corpus search relying on only one form will miss documents using the others.
Third, the county of Limerick must be distinguished from the city of Limerick. Medieval and early modern records frequently treat county and city as separate jurisdictions — a distinction that matters for probate records, land tenure instruments, assize records, and franchise grants.
Fourth, Irish county designations in Law Latin are particularly dense in records from the Tudor and Cromwellian plantation periods, the Court of Chancery in Ireland, and the Irish exchequer. Researchers working in English common law sources will encounter these terms only when Ireland-related matters came before English courts or Crown administration.

Historical Dictionary Support
Burrill's Law Dictionary disposes of this term in a single line: "Limerick county in Ireland," with attribution to a Latin dictionary (L. Lat. Dict.). This is the full extent of dedicated historical legal dictionary coverage, and it is sufficient for the term's narrow function. The entry correctly identifies the term as a geographical designation and implicitly categorizes it among the Latinized county names that populated pre-modern legal instruments — a class of terms Burrill treats with characteristic economy throughout his dictionary.
No substantive legal doctrine attaches to the term in Burrill or elsewhere. Historical legal dictionaries generally give these geographic Latin terms brief treatment because their meaning, once decoded, is not in dispute. What the dictionaries do not supply — and what researchers need — is the broader context of how Law Latin place names functioned in the documentary traditions of Irish legal administration, a gap that must be filled by reference to diplomatic and paleographic guides to Irish records rather than to law dictionaries.

Jurisdictional Note
The term appears almost exclusively in documents generated by or for the English and British administration of Ireland, spanning roughly the thirteenth century through the eighteenth. It has no currency in modern Irish or British legal usage, where plain English place names govern.

Encyclopedia Cross-Reference
For the distinct but etymologically adjacent legal concept of posse comitatus — the power of the county as a legal institution, from which the modern Posse Comitatus Act derives — see: Posse Comitatus Act — Restrictions on Domestic Military Operations and Exceptions (The Law Mind Military, Veterans & Admiralty Law Encyclopedia). Note that the shared word comitatus (county) is the only connection; that entry addresses United States federal law, not Irish administrative geography.
