The word "stink" is commonly used to describe an unpleasant odor. However, there are several synonyms that can be used to convey the same meaning such as odor, scent, smell, aroma, reek, and fragrance. The word "odor" is a general term for any smell, whereas "scent" refers to a pleasing smell. "Smell" and "aroma" are more subjective terms, as they can describe both pleasant and unpleasant odors. "Reek" is a more intense version of the word stink, typically used to describe a strong and unpleasant smell. "Fragrance" is a word used to describe a nice smell, typically associated with perfumes and other scented products.
