The wind, the breath and the Spirit
In John 3:8 the word appears twice in one sentence, meaning “wind” the first time and “Spirit” the second. Translators must pick, and the sentence loses its hinge either way. It is the clearest case in the New Testament of an English Bible being unable to say what the Greek said.
The same doubling runs back through the Old Testament: the ruach hovering over the waters in Genesis 1:2 and the breath breathed into Adam are the same word too.
The wind blows where it wishes. You hear its sound, but you do not know where it comes from or where it is going. So it is with everyone born of the Spirit.”
