word translates Gk. pneuma and Heb. ruah. Distinction between "soul" and "spirit" (as "seat of emotions") became current in Christian terminology (e.g. Gk. psykhe vs. pneuma, L. anima vs. spiritus) but "is without significance for earlier periods" [Buck]. L. spiritus, usually in classical L. "breath," replaces animus in the sense "spirit" in the imperial period and appears in Christian writings as the usual equivalent of Gk. pneuma. Meaning "supernatural being" is attested from c.1300 (see ghost
); that of "essential principle of something" (in a non-theological sense, e.g. Spirit of St. Louis) is attested from 1690, common after 1800. Plural form spirits "volatile substance" is an alchemical idea, first attested 1610; sense narrowed to "strong alcoholic liquor" by 1678. This also is the sense in spirit level (1768).
1599, "to make more active or energetic" (of blood, alcohol, etc.), from spirit
(n.). The verb meaning "carry off or away secretly (as though by supernatural agency)" is first recorded 1666. Spirited "lively, energetic" is from 1599.
