breath
/breθ/·브레스·noun
air taken into and expelled from the lungs
Old EnglishCEFR A2
Root
Proto-Germanic '*brēþaz' (smell, exhalation)
Proto-Germanic *brēþaz → Old English bræþ (smell, vapor, exhalation) → Middle English breth → Modern breath. Latin used spiritus (breath, spirit) — a separate root, source of English spirit, inspire.
In a word
English breath came straight from the Germanic branch. Latin grew the same meaning on a different root — spiritus (breath = spirit), which gave English spirit, inspire, expire, conspire. Above one breathing person stand two genealogies — Germanic family: breath (the body's air), breathe, breathless. Latin family: spirit (soul), inspire (to breathe in = to fill with inspiration), expire (to breathe out = to die or to lapse). The old thought that breath and soul are one word stands in English on two parallel roots.
Examples
Take a deep breath.
I am out of breath.
It took my breath away.
