When we smell something, we are detecting volatile organic compounds (odor molecules) that are released into the air. These molecules bind to receptors in our nose, sending signals to our brain that are interpreted as specific smells.

When you smell something, you are detecting molecules that are released into the air. These molecules travel through the air and enter your nasal passages, where they bind to receptors in your nose. These receptors then send signals to your brain, allowing you to perceive and identify different scents.
Smell can function as both a verb and a noun. As a verb, it describes the action of detecting odors with the nose. As an adjective, it describes something having a scent or odor.
The study of smell is called "olfaction." It involves the process of detecting and interpreting odors through the sense of smell.
