Synonym discussion

Sense: noun/1

All six words name what you notice with your nose, but they differ sharply in tone. 'Smell' is the neutral, all-purpose word — you can use it for fresh bread or rotten eggs ('the smell of the sea', 'a strange smell from the drain'). 'Scent' is neutral to mildly positive and often subtle ('the scent of wildflowers'); it is also the word used for animal tracking ('the dog followed the scent'). 'Odor' is more clinical and often negative in everyday English ('body odor', 'a chemical odor') — it appears frequently in scientific or safety contexts. 'Fragrance' is deliberately positive and is the standard word for perfumes, soaps, and pleasant manufactured smells ('the fragrance of her shampoo'). 'Aroma' is also positive but specifically describes food and drink smells ('the rich aroma of freshly brewed coffee'). 'Stench' is the strongest negative word, used for overwhelming rotten or decay smells ('the stench of rotting fish'). Choosing the right word transforms 'a bad smell' into something precise: 'a stale cigarette odor' vs 'the lingering aroma of roasted coffee'.

Etymology

Old EnglishMiddle EnglishModern English

The word 'smell' traces back to Old English *smyllan*, which meant 'to emit a smell or vapour'. It is related to *smēocan* ('to smoke') and *smoca* ('smoke'), suggesting the original idea was something like 'to give off a detectable vapour'. By around 1200, the word had developed both the 'give off an odour' and 'perceive an odour' meanings. The noun meaning 'the sense of smell' appeared in the mid-14th century, and the figurative 'characteristic quality' arose in the early 19th century.
