Definition

A person who has not yet reached the age of legal majority — the threshold age at which the law treats an individual as fully competent to exercise legal rights, enter binding contracts, and bear the full responsibilities of adult legal status. In nearly all U.S. jurisdictions today, that age is 18.

The term carries two related but distinct functions in legal usage:

1. Status designation. A minor is a person who, by reason of age alone, lacks full legal capacity. This affects the enforceability of contracts the minor enters, the minor's ability to consent to medical treatment, to vote, to sue in their own name, and to hold certain property rights independently.

2. Descriptive age marker. In historical civil law usage, "minor" was used as a comparative term — minor viginti quinque annis, meaning one who is less than twenty-five years of age. The threshold was not a fixed legal rule uniform across all contexts but varied by purpose and jurisdiction.

Common Language

Modern common usage (Wiktionary): Wiktionary's primary definition of minor as a standalone adjective or noun in general English carries the sense of lesser importance, smaller degree, or subordinate rank — as in a minor inconvenience or a college minor. As a noun referring to a person, the common usage largely mirrors the legal one.

Historical common usage (Webster's 1913): Webster's defines minor principally as an adjective — "inferior in bulk, degree, importance, etc.; less; smaller; of little account" — with its musical sense (minor key, minor third) as the secondary meaning. The noun sense referring to a person of young age is present but secondary.

The ordinary English sense of minor as simply "lesser" or "smaller" differs from its legal meaning, where the term operates not as a comparative but as a fixed legal status. A person is legally a minor or is not — there is no legal sense in which someone is "more minor" than another. Researchers working with historical sources should be alert to uses of minor in its adjectival, non-status sense even in legal texts, particularly in civil law contexts where the word appears as part of Latin phrases.

Common Confusion

MINOR vs. INFANT: In historical legal usage, infant and minor are functionally synonymous — both describe a person below the age of legal competence. Many historical dictionaries treat them as interchangeable, and older case law and statutes will use infant where modern law would say minor. Today, infant in ordinary usage means a very young child, which has caused confusion when the term appears in older legal instruments. Do not interpret infant in a historical legal document as limited to newborns or young children; it likely means any person below the age of majority.

MINOR vs. JUVENILE: Juvenile is a term of art primarily in the context of criminal and delinquency proceedings. A minor is the broader status category; juvenile typically refers to a minor in the specific context of the juvenile justice system. The two terms are not interchangeable in all contexts.

Recognized Forms

/SUBTYPES

Emancipated minor: A minor who has been legally released from parental control and disability — typically by court order, marriage, or military service — and who is treated as an adult for some or all legal purposes before reaching the age of majority.

Mature minor: A minor who, though not formally emancipated, is deemed sufficiently mature to consent to certain decisions (most commonly medical treatment) without parental involvement. This is a doctrine, not a formal status granted by court order. See Minors and Healthcare Law in the Law Mind Health Law & Bioethics Encyclopedia.

Why It Matters in Research

Age of majority has changed. The dominant historical threshold in English and American law was 21, inherited from common law and reflected in every major historical dictionary here. Anderson's states plainly: "A person not twenty-one years old." The shift to 18 as the standard age of majority in the United States occurred largely through state legislation in the 1970s, following the Twenty-Sixth Amendment (which lowered the voting age to 18). Researchers working with statutes, contracts, wills, or case law predating the 1970s must apply the 21-year threshold unless the document or applicable law specified otherwise.

Contextual variation survives even today. Even within modern law, the age threshold for specific purposes varies: the age of consent to sexual activity, the age of consent to medical treatment, the age to purchase alcohol, the age of criminal responsibility — none of these is universally tied to the majority age. A person can be a minor for contract purposes but not for criminal prosecution in the adult system. Research in any area touching minor status should identify the specific operative age threshold for the legal question at hand, not assume 18 governs everything.

Historical terminology trap. Because historical sources treat infant and minor as synonyms, corpus searches using only one term will miss significant material. Run searches on both terms when researching capacity, contracts, guardianship, or parental rights in older sources.

Guardianship and custody connections. Minor status is the predicate for guardianship — guardianship of the person terminates when the ward reaches majority. Researchers working on guardianship matters should connect to the family law corpus entries on appointment and termination, as the definition of minor directly controls when those proceedings begin and end.

Historical Dictionary Support

The four source dictionaries are in close agreement on the core definition, which is itself significant: minor as a person below the age of legal competence is one of the more stable terms in this corpus. All four sources trace the term to Roman civil law, with Black's (both editions) and Burrill's citing the Institutes directly for the minor viginti quinque annis formulation — one who is less than twenty-five years old. This reflects the civil law's use of 25 as a threshold of full legal competence, a higher bar than the English common law's 21.

Burrill's is the most thorough on etymology and comparative usage, noting that while civil law paired minor with major (as in major viginti quinque annis), the term major in this sense was not adopted into English legal usage. This is a useful observation for researchers encountering Latin-inflected legal texts.

Anderson's is the most economical: "A person not twenty-one years old; an infant." The identification of minority with infancy is explicit, and Anderson's cross-reference to majority is a reminder that the terms are correlatives — each defines the other.

What the historical dictionaries do not address: the mature minor doctrine, the emancipated minor as a formal legal category, and the legislative shift from 21 to 18 all postdate these sources. Researchers should not look to these dictionaries for guidance on modern capacity questions in healthcare or criminal contexts.

Jurisdictional Note

The age of majority is 18 in most U.S. states and in England and Wales, but some states set different thresholds for specific purposes. Mississippi historically maintained 21 as the general age of majority longer than most states. Outside the United States and United Kingdom, the age of legal majority varies and may be as high as 21 in some civil law jurisdictions, reflecting the older Roman law influence visible in the historical dictionary entries above.

The form of the minor scale is various. The strictly correct form has the third and sixth minor, with a semitone between the seventh and eighth, which involves an augmented second interval, or three semitones, between the sixth and seventh, as, 6/F, 7/G#, 8/A. But, for melodic purposes, both the sixth and the seventh are sometimes made major in the ascending, and minor in the descending, scale, thus: --See Major.  -- Minor term of syllogism (Logic), the subject of the conclusion.
