Etymology
The word "Spirit" (from the Latin spiritus meaning "breath") appears as either alone or with other words, in the Hebrew Bible (Old Testament) and the New Testament. Combinations include expressions such as the "Holy Spirit", "Spirit of God", and in Christianity, "Spirit of Christ".
The word Spirit is rendered as רוּחַ (ruach) in Hebrew-language parts of the Old Testament.[4] In its Aramaic parts, the term is rûacḥ.[5] The Greek translation of the Old Testament, the Septuagint, translates the word as πνεῦμα (pneuma).[4] This is the same word that is used throughout the New Testament, written originally in Greek.
The English term "Spirit" comes from its Latin origin, spiritus, which is how the Vulgate translates both the Old and New Testament concept.[7] The alternative term, "Holy Ghost", comes from Old English translations of spiritus.[8]
