The English word "spirit" comes from the Latinspiritus, meaning breath.
Etymology
The English word "spirit" comes from the Latinspiritus, meaning "breath" (compare spiritus asper), but also "soul, courage, vigor", ultimately from a PIE root *(s)peis- ("to blow"). In the Vulgate, the Latin word translates Greek (πνευμα), pneuma (Hebrew (רוח) ruah), as opposed to anima, translating psykhē. The word was loaned into Middle English via Old Frenchespirit in the 13th century.
The distinction between soul and spirit became current in Judeo-Christian terminology (e.g. Greek. psykhe vs. pneuma, Latin anima vs. spiritus, Hebrew ruach vs. neshama or nephesh; in Hebrew neshama from the root NSHM or breath.)
