Definition
Placitum (plural: placita) is a Latin term of medieval and early common law origin carrying several related but distinct meanings, each tied to the formal proceedings of courts. Modern legal usage is rare; the term survives primarily in historical records, old nisi prius forms, and scholarship on the development of English procedure.
1. A public deliberative assembly. In its earliest English sense, a placitum was a great public assembly presided over by the king, comprising men of varying rank, convened to deliberate on affairs of state. This usage is essentially political rather than judicial.
2. A court or judicial tribunal. Placita came to denote a court itself — including a lord's court — and appeared as the formal style or title heading old nisi prius records, marking the commencement of court proceedings.
3. A suit, cause, or judicial proceeding. More narrowly, placitum described a specific matter before a court: a cause of action, a trial, or the proceeding as a whole.
4. A plea or pleading. In procedural usage, placitum referred to a plea — the formal allegation or answer entered by a party — and by extension, to pleadings collectively. This sense is the most durable in records and treatises.
5. An agreement between parties (civil law usage). In Roman and civil law, placitum carried the sense of a consensual arrangement — that which it pleased the parties to settle between themselves. Burrill notes the root in placere (to please), which also underlies the imperial sense: a decree or ordinance as the pleasure of the sovereign.

Common Language
Modern common usage (Wiktionary): A public court or assembly in the Middle Ages; a court or cause in court; a plea or pleading; a judicial decision.
Historical common usage (Webster's 1913): A public court or assembly in the Middle Ages presided over by the sovereign; a court, or cause in court; a plea, pleading, judicial proceeding, or suit.
The common definitions here track legal usage closely because placitum never fully crossed into non-legal English. The gap worth noting is one of precision: the general sources collapse four legally distinct senses into an undifferentiated list. A researcher encountering placitum in a specific record must determine which sense is operative — the word functioning as the name of a court is materially different from its function as the title of a plea or the label for a cause of action.

Common Confusion
Placitum, placita, and plea are frequently treated as interchangeable in secondary literature, but they are not equivalent. Placita is simply the plural of placitum and can refer to courts, proceedings, or pleadings collectively depending on context. Plea in modern English has narrowed considerably — in criminal procedure it refers almost exclusively to the defendant's response to a charge; in civil procedure, to a formal responsive pleading. Placitum in its historical sense was broader, encompassing the entire proceeding or cause, not merely one party's response. Researchers should also distinguish placitum from placitum regis (pleas of the crown) and placita communia (common pleas), which were formal institutional designations for categories of jurisdiction, not merely descriptive phrases.

Recognized Forms
/SUBTYPES
Placita coronae — Pleas of the Crown. Criminal matters cognizable by the king's courts; the jurisdictional category from which the Crown side of King's Bench developed.
Placita communia — Common Pleas. Civil matters between subject and subject; the jurisdictional category that gave its name to the Court of Common Pleas.
Placitum conventionale — A conventional or agreed plea; a matter arranged by agreement of parties, closer to the civil law sense of placitum as consensual arrangement.

Why It Matters in Research
Researchers working in the Law Mind corpus will encounter placitum across several distinct documentary contexts, and misreading its operative sense in any given source is a live risk.
In early plea rolls and nisi prius records, placita appears as a heading — a formal title marking the opening of a court record, not a reference to any particular plea or proceeding within it. Reading placita here as "the pleas" in the substantive sense will produce a misreading of the document's structure.
In treatises on pleading — particularly those tracing the development of English common law procedure — placitum shifts to its procedural meaning and refers to the plea itself. Blackstone's Commentaries use it in this sense, and Anderson's citation to 2 Bl. Com. 305 grounds the plea-and-pleading sense firmly in that tradition.
The civil law sense (agreement of parties) appears in sources drawing on Roman law or the continental tradition and will not always be clearly flagged as a different usage. Burrill preserves this distinction carefully; Black's and Anderson's less so.
The term's presence in records "down to the present" (as Burrill notes) means it persists in formal legal instruments well past the medieval period. A nineteenth-century record using placita is likely carrying the formal heading sense or the pleading sense, not the deliberative assembly sense. Researchers should calibrate their reading to document type and date.
Jurisdictional variation also matters: the placita coronae / placita communia distinction was fundamental to the organization of English royal justice and maps directly onto the later institutional separation of King's Bench from Common Pleas. Any corpus research touching on English court structure or jurisdiction will need this framework.

Historical Dictionary Support
The five source dictionaries substantially agree on the range of meanings but differ in emphasis and completeness.
Black's (both editions) and Anderson's treat placitum primarily through its English common law senses: the public assembly, the court, the suit, and the plea. Black's first edition is the most complete, cataloguing all senses in sequence. The second edition adds the label "Decree; determination" as a lead gloss — a useful addition that captures the sense of placitum as a judicial determination or ruling, which the first edition subsumes without separately flagging.
Burrill's is the most philologically precise of the group. His entry roots the term in placere, distinguishes the civil law sense (consensual agreement) from the procedural sense (plea or proceeding), and notes the term's persistence in formal records. This is the most useful entry for researchers working across civil and common law sources.
Rapalje & Lawrence offers only a cross-reference to placita and plea, which is accurate as far as it goes but unhelpful in isolation.
Anderson's entry is notable for flagging the Latin abbreviation "L." at the outset — a reminder that placitum is a term of art appearing in Latin-language records and requires translation competence as well as legal knowledge. Anderson also links plea and pleading directly to Blackstone, grounding the usage in a specific treatise tradition.
What the historical dictionaries largely omit: the significance of the placita heading in the structure of court records as a formal document element, and the distinction between placitum as an institutional label (Court of Common Pleas) and placitum as a description of a particular proceeding. Researchers relying solely on the dictionary definitions will have the vocabulary but not the documentary grammar.

Jurisdictional Note
Placitum as a living term of art is confined to historical English and Anglo-American common law sources and to civil law scholarship. It has no current operational meaning in U.S. or English statutory law. Civil law jurisdictions using Latin-based terminology may retain analogous concepts under different vocabulary. Researchers in Scottish legal history should note that placita appears in early Scots records with similar but not identical institutional meanings.
