sprite (n.)

mid-13c., "life, the animating or vital principle in man and animals," from Anglo-French spirit, Old French espirit "spirit, soul" (12c., Modern French esprit) and directly from Latin spiritus "a breathing (of respiration, also of the wind), breath;" also "breath of a god," hence "inspiration; breath of life," hence life itself.

The Latin word also could mean "disposition, character; high spirit, vigor, courage; pride, arrogance." It is a derivative of spirare "to breathe," and formerly was said to be perhaps from a PIE *(s)peis- "to blow" (source also of Old Church Slavonic pisto "to play on the flute"). But de Vaan says the Latin verb is "Possibly an onomatopoeic formation imitating the sound of breathing. There are no direct cognates." Compare conspire, expire, inspire.

In English it is attested from late 14c. as "divine substance, divine mind, God;" also "Christ" or His divine nature; also "the Holy Ghost; divine power." Also by late 14c. as "the soul as the seat of morality in man," and "extension of divine power to man; inspiration, a charismatic state; charismatic power," especially in reference to prophecy.

The meaning "supernatural immaterial creature; angel, demon; an apparition, invisible corporeal being of an airy nature" is attested from mid-14c. The word is attested by late 14c. as "ghost, disembodied soul of a person" (compare ghost (n.)). Spirit-rapping, colloquial for spiritualism in the supernatural sense, is from 1852. Spirit-world "world of disembodied spirits" is by 1829.

It is attested from late 14c. as "essential nature, essential quality." The non-theological sense of "essential principle of something" (as in Spirit of St. Louis) is attested from 1680s and was common after 1800. The Spirit of '76 in reference to the qualities that sparked and sustained the American Revolution of 1776 is attested by 1797 in William Cobbett's "Porcupine's Gazette and Daily Advertiser."

It also is attested from mid-14c. in English as "character, disposition; way of thinking and feeling, state of mind; source of a human desire;" in Middle English freedom of spirit meant "freedom of choice." It is attested from 1580s in the metaphoric sense of "animation, vitality," and by c. 1600 as "frame of mind with which something is done," also "mettle, vigor of mind, courage."

From late 14c. in alchemy as "volatile substance; distillate" (and from c. 1500 as "substance capable of uniting the fixed and the volatile elements of the philosopher's stone"). Hence spirits "volatile substance;" the sense of which narrowed to "strong alcoholic liquor" by 1670s. This also is the sense in spirit level (1768), so called for the liquid in the clear tube.

According to Barnhart and OED (1989), the earliest use of the word in English mainly is from passages in the Vulgate, where the Latin word translates Greek pneuma and Hebrew ruah. A distinction between soul and spirit (as "seat of emotions") became current in Christian terminology (such as Greek psykhē and pneuma, Latin anima and spiritus) but "is without significance for earlier periods" [Buck]. Latin spiritus, usually in classical Latin "breath," replaced animus in the sense "spirit" in the imperial period and appears in Christian writings as the usual equivalent of Greek pneuma.

in brief, conceive light invisible, and that is a spirit. [T. Browne, " Religio Medici"]

1590s, "full of spirit or vigor, brisk, lively," from spright, an early 16c. variant of spirit (n.) and also of its doublet sprite, + -ly (1). So, in the manner of a sprite, or with much spirit. The form spritely also is attested from 1590s. "Sprightly is the common spelling, the literal meaning and therefore the proper form of the word being lost from view" [Century Dictionary].
