Definition
A Latin-derived verb found in old English legal records meaning to bring an action, to prosecute, or to sue. Actionare functioned as a verbalized form of the noun actio (action), used in medieval and early modern legal instruments to express the act of initiating or pursuing legal proceedings. It carries no specialized technical meaning beyond this functional description — it is, essentially, the act of suing, rendered in Law Latin.
Why It Matters in Research
Actionare is an archaic term encountered almost exclusively in medieval and early modern English legal records, chronicles, and pleading documents. Researchers consulting primary sources from this period — particularly old plea rolls, monastic records, or chronicle accounts of legal disputes — may encounter actionare or its inflected forms without any surrounding explanation, since contemporaneous scribes treated the word as self-evident.
The principal research trap is assuming actionare carries the doctrinal weight of the English term "action." In modern and even early modern usage, "action" implies a structured procedural category with defined elements and remedies. Actionare, by contrast, is purely verbal — it describes the act of commencing proceedings, not the nature or form of those proceedings. A source that reads "actionavit" (he brought an action) tells the researcher that legal proceedings were initiated; it says nothing about what form of action was pursued or whether it succeeded.
The references in all three source dictionaries to Thorn's Chronicle and Whishaw's New Law Dictionary locate the term firmly in the antiquarian and chronicle literature. Researchers tracing the term should expect to find it in documentary sources rather than treatises, and should treat it as a formulaic scribal word rather than a contested legal concept. It does not appear in common law pleading manuals as a term of art, and it is absent from equity or ecclesiastical practice materials.
No meaningful jurisdictional variation in usage is documented — the term appears to have been a general feature of medieval English (and possibly continental) Latin legal drafting rather than a product of any particular court or region.
Historical Dictionary Support
The three source dictionaries — Black's (1st and 2nd editions) and Burrill's — are in complete agreement on this term. All three define it identically, cite the same sources (Thorn's Chronicle and Whishaw), and frame it as a term from "old records." This uniformity reflects a shared antiquarian lineage: Black's and Burrill's are both drawing from the same narrow documentary base rather than from independent legal analysis.
What the historical dictionaries do not address is how the term actually appeared in practice — whether it was used in formal pleadings, in chronicle narrations of disputes, or in informal administrative records. The citation to Thorn's Chronicle suggests at least one use in a narrative rather than purely procedural context, which is consistent with the word's role as a descriptive verb rather than a technical term of art. Researchers should not treat the dictionary entries as exhaustive accounts of usage; they are, at most, pointers toward the primary sources themselves.
