Definition
In legal usage, chaperon carries two narrow historical senses:
1. A hood or bonnet worn by Knights of the Garter as part of the formal habit of that order of chivalry.
2. A small heraldic escutcheon affixed to the forehead of horses drawing a hearse in ceremonial or state funerals.
Neither sense corresponds to the term's dominant modern meaning. As a legal term of art, chaperon belongs almost entirely to the vocabulary of heraldry, ceremonial protocol, and the law of arms. It does not appear as a functional term in common-law doctrine, contract, tort, or procedure.

Common Language
Modern common usage (Wiktionary): An adult who accompanies or supervises one or more young, unmarried men or women during social occasions, typically to prevent inappropriate social or sexual interactions.
Historical common usage (Webster's 1913): A matron who accompanies a young lady in public for propriety, or as a guide and protector. Webster's also records the hood meaning and the funeral horse device.
The gap between common and legal meaning is sharp and worth flagging. Every historical legal dictionary consulted defines chaperon exclusively by the heraldic and ceremonial senses — the hood and the funeral escutcheon — and ignores entirely the matron-supervisor meaning that dominated ordinary social usage in the same period. A researcher encountering chaperon in legal text should not assume the social-supervision meaning; the legal sources are unanimous in treating this as a term of heraldry and ceremonial dress. Conversely, a researcher working in social history, family law, or the law of domestic relations will find the chaperon as social guardian completely absent from the standard legal dictionaries, which may itself be instructive.

Why It Matters in Research
The principal research trap is semantic drift in context. A legal document from the eighteenth or nineteenth century using chaperon could plausibly invoke any of three meanings — the heraldic escutcheon, the chivalric hood, or the social guardian — and the legal dictionaries resolve only two of them. Researchers working in:
Heraldry and the law of arms: The escutcheon meaning is the operative one. The chaperon in this sense is a functional element of funeral ceremony with potential relevance to questions of rank, precedence, and the proper display of armorial bearings at funerals — matters that carried legal weight in English practice under the College of Arms.
Orders of chivalry and ceremonial law: The hood meaning connects to the formal constitutions and statutes of the Order of the Garter, which are themselves quasi-legal instruments governing membership, privileges, and regalia.
Social and domestic history intersecting with law: The matron-guardian meaning, entirely absent from the legal dictionaries, is the meaning most likely to appear in social legislation, custody proceedings, school regulations, and cases involving the supervision of young women. Researchers should not expect the standard legal dictionaries to be a guide here; common-law reporters and statutory materials are the appropriate sources.
The reliance of every major historical dictionary on Wharton as the single authority for this entry warrants caution. The definition is thin, recycled verbatim across editions and compilers, and carries no doctrinal elaboration. It is descriptive rather than normative — none of the sources explains what legal consequences, if any, attached to the proper or improper use of a chaperon in the heraldic sense.

Historical Dictionary Support
Black's Law Dictionary (1st and 2nd editions) and Rapalje & Lawrence reproduce the same two-part definition in nearly identical language, all attributing to Wharton. The uniformity is itself notable: no compiler added doctrinal gloss, case citation, or expanded treatment across successive editions. This is a dictionary entry that was borrowed rather than developed.
Wharton's Law Lexicon, the common source, treated chaperon as a curiosity of heraldic vocabulary rather than a working legal concept. The result is that every major historical legal dictionary in the Law Mind corpus offers the same minimal entry, and none of them engages with the socially dominant meaning of the word that was well established in contemporaneous general usage — including, as Webster's 1913 confirms, at the time these legal dictionaries were compiled.
What the historical sources miss: The complete absence of the chaperon-as-social-guardian from all three legal dictionaries is a genuine lacuna. Whether this reflects editorial judgment that the concept was not yet sufficiently legalized, or simply Wharton's original framing being uncritically repeated, the practical effect is that legal lexicography offers no guidance on a sense of the word that appeared in real legal contexts.

Jurisdictional Note
The heraldic and ceremonial meanings are English in origin and most directly relevant to English law, the law of arms, and the jurisdiction of the College of Arms. American legal practice has no equivalent institution, and American legal sources rarely invoke chaperon in the heraldic sense. The social-guardian meaning, by contrast, appeared in both English and American contexts in the nineteenth and early twentieth centuries.
