teetotalism

Teetotalism refers to the total abstinence from alcohol. It carries a stronger connotation than simply "not drinking," as it often implies a principled, moral, or lifelong commitment rather than a temporary choice or a medical necessity. While someone might avoid alcohol for a diet, a person practicing teetotalism does so as a lifestyle or ideological stance.

In modern usage, the term can feel slightly old-fashioned or formal, often evoking the historical temperance movements of the 19th century. In casual conversation, people are more likely to say they are "sober" or "don't drink," whereas "teetotalism" is used when discussing the philosophy or the strictness of the practice.

Distinguish this noun from the adjective "teetotal." A person is "teetotal" (e.g., "He is a teetotal man"), while the practice itself is "teetotalism."
