What’s the difference between breath and breathe?

If somebody said, “I thought my train my think,” you’d be quick to say, “don’t you mean, ‘your train of thought?’” Terms like think vs. thought are exactly like breath vs. breathe. While commonly confused words like breathe vs. breath share related meanings, one term is an object, and the other is an action. 

The word breath is a noun that’s defined as the air we inhale and exhale during respiration, but the term “respiration” is actually just a fancy way of saying the other confusing word: breathe. The word breathe is a verb, so it’s an action as opposed to a thing–– like breath

Another major difference between breath and breathe is that each word is pronounced very differently. For example: 

  • The noun breath is pronounced like “breth” with a short e sound similar to words like “death” or “meth.”
  • The verb breathe is pronounced as “breeth,” and contains a long e sound similar to words like “seethe,” “teethe,” or “wreathe.” 

Counting vowels is another common mistake many students make while learning breathe vs. breath. Counting vowels helps for memorizing words like loath vs. loathes, but it doesn’t help here. Since we spell the noun as “breathes” after pronouns like he, she, or it, either “breathes” or “breathe” contain an extra letter e. 

The best way to remember the difference between breath and breathe is to understand they mean scientifically before their grammatical functions. This way, we can understand how drastically different they are as a verb or a noun.

Respiration is breathing, air is breath

Respiration is an essential process for all living organisms to produce cellular energy. The verb breathe represents the act of respiration that’s specific to mammals because their cellular energy derives from oxygen.

Mammalian respiratory systems consist of lungs, a diaphragm, internal airways, blood cells, and muscles, which allow them to inhale and exhale air through their mouth and nose and into their lungs. Inhalation is the process of “breathing in” air to the lungs, while exhalation is the act of “breathing out” air from the lungs. 

The air inhaled into the lungs is absorbed by tiny, grape-like structures called alveoli. When you breathe in, the alveolar sacs expand to collect air and deposit oxygen into your circulatory system. While this occurs, alveoli simultaneously exchange oxygen for carbon dioxide. When you breathe out, carbon dioxide exits the lungs through your breath. Thus, the air is “breath,” and respiration is “to breathe.”

Does air breathe?

The easiest way to confuse breath and breathe is to misunderstand their non-literal interpretations. Because the terms both involve air, the vital essence of human survival, people have always related air to concepts in a metaphorical manner. 

As you will find in the definitions and phrases containing breathe or breath, the English Language utilizes these terms to describe the spirit, life, death, fragrance, speech, or even athletic apparel. The key is to understand how breath and breathe come full circle to the topic of respiration and how they perform as a noun vs. a verb. 

Where do the words breath and breathe come from?

The noun breath entered the English Language before the 12th century and nearly two centuries before the verb breathe. The word breath comes from Middle English ‘breth,’ which derived Old English brǣth for ‘smell’ or ‘scent.’ Breathe derives from the terms breth (breath) and the Middle English term brethen, which translates to ‘exhale’ and ‘steam.’ 

What does breath mean?

The word breath is a noun, and it’s defined as the air inhaled or exhaled through the lungs. Examples of breath in a sentence include,

“When it’s cold outside, you can see your breath.”
“If you dive into the water, be sure to hold your breath.” 

We can also use the noun breath to encompass the act of breathing in its entirety. In this case, the word breath is also synonymous with rest or a “time-out.” 

For example, 

“After sprinting, I jog to catch my breath.” 
“Let’s stop and take a deep breath.” 

Outside of the literal meaning of breath, we also define the noun through metaphorical interpretations to describe air, fragrance, and life. For example,

1. A gentle breeze, waft, or zephyr. 

Ex.: “A wisp of spring breath raised the garden to life once again.”

2. A small suggestion, hint, or imperceivable sign.

Ex.: “He admitted his crimes without a breath of remorse.”

3. A barely perceived utterance, murmur, or pouty sigh.
