The term 'smells' can be described in a variety of ways, such as WHIFFS (6 letters), ODORS (5 letters), REEKS (5 letters), and sniffs (6 letters). WHIFFS are short, light bursts of scent, while ODORS are more sustained and often unpleasant. REEKS are strong, pungent smells that are often associated with something bad or rotten. Sniffs are quick inhalations of air through the nose to detect a smell. All of these words describe the sense of smell, which is the ability to detect and identify ODORS.
