I give the etymology of the natural words "spirit"(first paragraph, see full entry from the link) and spirituality:
spirit (n.)
mid-13c., "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 (respiration, and of the wind), breath; breath of a god," hence "inspiration; breath of life," hence "life;" also "disposition, character; high spirit, vigor, courage; pride, arrogance," related to spirare "to breathe," perhaps from PIE *(s)peis- "to blow" (source also of Old Church Slavonic pisto "to play on the flute"). But de Vaan says "Possibly an onomatopoeic formation imitating the sound of breathing. There are no direct cognates."

spirituality (n.)
early 15c., "the clergy," also "ecclesiastical property; things pertaining to the Church," from Middle French spiritualite, from Late Latin spiritualitatem (nominative spiritualitas), from Latin spiritualis (see
spiritual). Meaning "quality of being spiritual" is from c. 1500; seldom-used sense of "fact or condition of being a spirit" is from 1680s. An earlier form was spiritualty (late 14c.).
