The breath of life in man.
The intelligent, immaterial, and immortal part of human beings.
Also, (superhumanly)
an angel or demon.
Also, (divinely) God,
Christ's Spirit; the
Holy Spirit.

Having therefore these promises,
dearly beloved,
let us cleanse ourselves from all
filthiness of the flesh and spirit,
perfecting holiness in the fear of God.

2 Corinthians 7:1
