What Does Smell Mean?
Smell is the sensation you perceive through your nose when you inhale . It refers both to the physical act of detecting odors and to the odor itself. As a noun, “smell” means the quality of something that you notice through your nose, whether pleasant or unpleasant. As a verb, it means to perceive an odor or to give off a particular odor .
Example sentences:

Core Meaning of Smell
At its heart, “smell” connects to one of the five senses. It is the most general and neutral word for anything you detect with your nose . Unlike words like “aroma” or “stench,” which carry a built-in judgment, “smell” simply states that an odor exists. The tone comes from the context: “the smell of cookies” sounds pleasant, while “the smell of garbage” sounds unpleasant.
Beyond the literal meaning, “smell” can also refer to the act of detecting something—the physical process of inhaling to perceive an odor . Additionally, it has a figurative meaning: to sense or suspect something instinctively, as in “I smell trouble” .
