An "odor" is a general term for a smell, which can be either pleasant or unpleasant. It's a sensory perception detected by your nose. Unlike "aroma," which usually implies a pleasant scent, "odor" is neutral and can describe any smell. Think of the odor of freshly cut grass or the odor of garbage ποΈ. Odors can trigger memories and emotions, both positive and negative. Itβs a broad term for anything that stimulates your sense of smell.
