Etymology
Origin of breath
First recorded before 900; Middle English breeth, breth, Old English brǣth “smell, exhalation”; akin to German Brodem “vapor, steam”
Explanation
Breath is the process of taking air in and out of your lungs. It’s also the air you inhale and exhale, or a slight movement of air, like a breeze. Breath comes from the Old English braeth (“scent" or "smell”). Many figures of speech originate with the idea that breathing deeply energizes or calms us. You can "catch your breath" by slowing down, and you might "take a breath" by taking a break or walking away from a stressful situation. A "breath of fresh air" might be just that, or, metaphorically, it might signal the arrival of something new and different that invigorates us or refocuses our attention.
