Definition
In Roman and civil law, adolescentia denotes the intermediate stage of life between puberty and majority — the period during which a person was recognized as no longer a child but not yet fully capable in law. Under the civil law framework, adolescentia began at fourteen years of age for males and twelve for females (the ages at which puberty was legally presumed), and continued until the age of majority, generally fixed at twenty-five in Roman law.
The term is not a modern common law concept. It belongs to the Roman law taxonomy of legal capacity, which divided human life into structured stages — infancy (infantia), approaching puberty (impuberes), adolescence (adolescentia), and full majority — each carrying distinct legal consequences for contractual capacity, guardianship, and personal liability.

Common Language
Modern common usage (Wiktionary): The period of human development between childhood and adulthood; roughly equivalent to the teenage years. Used broadly in medicine, psychology, and sociology without fixed age boundaries.
Historical common usage (Webster's 1913): "The state of growing up from childhood to manhood or womanhood; youth, or the period of life between puberty and majority." Webster's fixes no rigid legal ages.
The gap here is structural: ordinary usage treats adolescence as a developmental and social concept with fluid boundaries. The civil law term adolescentia is a technical legal stage with fixed age thresholds tied to Roman law's system of guardianship and capacity, not to biology or social maturity. A researcher reading the word in a civil law source must not import the imprecision of the common meaning.

Why It Matters in Research
This is a term of art in Roman and civil law sources. Researchers will encounter it primarily in treatises on Roman private law, early civil law commentaries, and historical works that draw on the Corpus Juris Civilis tradition. It will not appear as an operative term in common law jurisdictions, and its presence in an English-language source almost always signals a learned or comparative law discussion rather than positive domestic law.
The key research trap is anachronism. Modern readers may assume adolescentia maps cleanly onto contemporary legal ages — the age of criminal responsibility, the age of consent, or the age of majority as defined by modern statutes. It does not. Under Roman law, adolescentes remained subject to the curator (a form of guardianship distinct from the tutor governing infantes and impuberes) and could not independently complete certain legal transactions without the curator's assistance. This protective regime for adolescentes persisted until age twenty-five, far older than any modern age-of-majority threshold in common law systems.
Burrill's entry cross-references Mackeldey's Compendium of Modern Civil Law (1 Mackeld. Civ. Law, § 126), a standard 19th-century civil law authority used in American courts and law schools in jurisdictions with civil law roots — particularly Louisiana. Researchers working in Louisiana legal history or in comparative private law contexts should follow that thread.
The gendered age differential embedded in the definition (fourteen for males, twelve for females) reflects the Roman law presumption of puberty at fixed ages rather than biological determination. This distinction carried forward into canon law discussions of marriage capacity and will appear in ecclesiastical law sources as well as civil law treatises.

Historical Dictionary Support
Burrill's is the only source in the Law Mind shelf that includes this term, and his entry is characteristically spare: a definition, the governing age thresholds, and a citation to Mackeldey. This is consistent with Burrill's treatment of Latin civil law terms — functional identification rather than extended exposition.
What the historical dictionary record does not capture is the guardianship architecture that gives adolescentia its practical legal significance. The distinction between tutela (guardianship of the impubes) and cura (curatorship of the adolescens) is the mechanism through which the age classification actually operated in Roman law. Researchers who stop at the dictionary definition will miss the doctrinal consequence. Secondary civil law treatises — Mackeldey, Savigny, and Puchta in the 19th-century tradition — provide the fuller account.

Jurisdictional Note
Adolescentia as a term of art has no operative role in modern common law jurisdictions. It retains historical relevance in Louisiana, Quebec, and other mixed civil law systems where Roman law foundations inform private law doctrine, and in any jurisdiction where courts or scholars have engaged in comparative or historical analysis drawing on the Corpus Juris Civilis.
