Breathiest → It is formed from "breath" (from Old English "bræð", meaning the air taken in or expelled from the lungs) and the suffix "-iest" (meaning most). The word "breathiest" describes something that has the most breath or is characterized by a lot of breath, often used to describe a voice or sound that is airy or light.
Think of 'breath' as the air we take in and 'iest' as indicating the most — so 'breathiest' means having the most air or being very airy.
