Majority

Chambers's Encyclopaedia, Volume 6: Humber to Malta, p. 816

Majority is the age at which a person acquires the status of a person sui juris—i.e. is able to manage his or her own affairs. This age in the United Kingdom is twenty-one. Under that age persons in England and Ireland are called infants, and are more or less subject to guardians, who manage for them their property. See INFANT.
