What does sniffed mean?
Sniffed is the past tense and past participle of sniff, a verb that describes taking a short breath through the nose to detect an odor or examine the air. In its most ordinary sense, it is transitive: a person or animal sniffs a flower, food, or the surrounding air, often briefly and deliberately. The word can also be used figuratively in the informal phrase “sniff out,” meaning to discover or investigate something, as in finding a hidden clue or opportunity. A third, less common use is “sniff at,” where the sound or gesture conveys contempt or dismissal. “Sniffed” is understood in both British and American English, although its figurative uses tend to sound conversational rather than formal. Its short, vivid wording makes it especially effective in descriptions of careful detection: an animal tracing a scent, a person testing the air, or someone looking for a sign of trouble. Unlike a neutral report that something “smelled,” “sniffed” highlights the active, searching gesture and often a degree of curiosity or suspicion. That combination of literal sensation and investigative metaphor makes it a useful word in both precise description and lively prose.

Where does sniffed come from?
Sniff has Germanic roots and is cognate with Dutch snuffen and German schnüffeln, all associated with drawing air through the nose to smell or investigate. It is also related to snuff and snuffle, which preserve related senses involving smelling or nasal sounds. Sniffed is simply the regular past-tense and past-participle form of sniff, so its grammatical development adds no separate etymological layer.
