TEETOTALER

n. one who abstains from alcoholic drinks

Teetotalism is the practice and promotion of complete (or T-total) abstinence from alcoholic beverages. A person who practices (and possibly advocates) teetotalism is called a teetotaler or teetotaller (plural teetotalers or teetotallers.)People generally choose teetotalism for religious, health, family, and/or social reasons. That does not mean that they never drink anything at drinking establishments. Water, juice, and soft drinks usually are served.In some cases, teetotalism is not a practice by choice. It can be forced by allergy. Such a person may be referred to as someone who has been teetotaled. An allergy to alcohol can develop later in life, even after a person has long consumed alcohol.
