Definition
A Latin term of medieval legal usage with three distinct applications in old English law:
1. A chapter or small division of a written legal instrument or text — a head or subdivision within a document, corresponding to what modern drafters would call a section or article.
2. An assembly or body of ecclesiastical persons — the chapter of a cathedral or collegiate church, being a collective body of canons or clergy constituted under one governance structure and capable of acting corporately.
3. One of the formal ceremonies or solemnities attending the creation of an earl or marquis in the English peerage — specifically the cappa honoris, the cap of honor, which was conferred as part of the investiture ritual.
The three meanings are distinct in application but share the same root concept: a governing head or organized unit, whether textual, institutional, or ceremonial.

Common Language
Modern common usage (Wiktionary): In botany, a densely clustered inflorescence composed of many florets arising from a flat or platform-like base (as in a daisy or clover head). In anatomy, a small protuberance on a bone forming part of a ball-and-socket joint, or the head-like mouthpart of a tick.
Historical common usage (Webster's 1913): A thick head of flowers on a very short axis, such as a clover top or dandelion; also a knob-like protuberance at the end of a bone or cartilage.
The common meanings — botanical and anatomical — share the diminutive-of-head etymology with the legal term but have no functional overlap. A researcher encountering capitulum in a legal or ecclesiastical document should not import botanical or anatomical connotations; the legal sense is entirely structural or institutional.

Recognized Forms
/SUBTYPES
As applied in old English legal sources, the term carries three recognized uses that researchers should distinguish:
CAPITULUM as textual division: Appears in references to chapters of statutes, codes, or canonical compilations. Functionally equivalent to chapter (Latin caput or capitulum) in the structural sense of a numbered or headed division.
CAPITULUM as ecclesiastical body: The chapter of a cathedral church — the assembly of canons who govern the cathedral and, in some periods, elected bishops. This is the corporate, institutional sense. The capitulum in this sense had legal standing, could hold property, and could litigate.
CAPITULUM as peerage ceremony: The conferral of the cappa honoris in the creation of an earl or marquis. This is a ceremonial or heraldic use, narrower in scope and largely of antiquarian interest.

Why It Matters in Research
Researchers working in old English ecclesiastical law, canonical sources, or medieval statutory materials will encounter capitulum in all three senses, sometimes without clear signal as to which applies. Context is the only reliable guide.
The textual division sense is frequent in canon law compilations and early English statutory references. When a source cites to a capitulum of a given document, it is pointing to a numbered section — the equivalent of "chapter" in the modern sense of legislative subdivision.
The ecclesiastical body sense carries significant legal weight in pre-Reformation English law and in canon law generally. The capitulum of a cathedral had defined rights, property interests, and procedural capacities in both ecclesiastical and secular courts. Researchers tracing cathedral property, advowsons, episcopal elections, or benefice disputes will encounter the capitulum as a corporate legal actor. Confusion between the body and its presiding officer (the dean, or the bishop as head) is a common research hazard.
The peerage ceremony sense is narrow but occasionally surfaces in historical sources discussing the formal investiture of earls and marquises. Burrill cites Bacon's Works for this usage, indicating it was recognized in legal and ceremonical literature but is not a working legal concept in the way the other two senses are.
Researchers should also note that capitulum in its plural form (capitula) appears frequently in canonical and conciliar documents as a general term for the articles or heads of an instrument — a usage that blends the textual division sense with something closer to a formal list of charges or propositions. This plural form is common in ecclesiastical proceedings and in records of church councils.

Historical Dictionary Support
Burrill's Law Dictionary is the primary source for this entry and provides all three recognized meanings. Burrill traces the word accurately as a diminutive of caput and cross-references Spelman, Termes de la Ley, and Cowell — the core shelf of old English legal lexicography — for the chapter and ecclesiastical assembly senses. The Bacon citation grounds the peerage/ceremonial sense.
What Burrill does not address: the canonical law usage of capitula as articles or heads of accusation in ecclesiastical proceedings, which is well-attested in canon law literature and appears in historical sources researchers are likely to encounter. Burrill's entry is useful as a starting point but is thinner than the term's actual range of use in primary sources would warrant.
Spelman's Glossarium Archaeologicum and Cowell's Interpreter (both referenced by Burrill) provide fuller treatment of the ecclesiastical body sense and are worth consulting directly for pre-Reformation English church law research. Termes de la Ley handles the textual division sense most directly.
No significant disagreement exists among the historical dictionaries on the core meanings; the variation is in depth of treatment rather than substance.

Jurisdictional Note
Capitulum as a legal term of art is primarily a feature of English ecclesiastical law and historical English statute drafting. Researchers working in Scottish ecclesiastical history will encounter the term in similar senses but within a distinct canonical and presbyterian institutional framework. Civil law jurisdictions use capitulum in canonical Latin sources with comparable meanings, but the corporate rights and property law consequences vary substantially from English common law treatment.
