Etymology

The word "odour" traces back to Latin odor, meaning "smell" or "scent." It entered Middle English via Old French odur or odeur, retaining its core meaning. The suffix -our (later simplified to -or in American English) is derived from Latin -or, used to form nouns denoting a condition or quality. Over time, "odour" has often carried a neutral or negative connotation, distinguishing it from more positive terms like "scent" or "aroma."

  3. The chemical left a sharp odour in the lab.

  5. The flowers released a sweet odour in the evening air.
