Linguistic Origin & Historical Etymology

Derived from the English nouns 'odor' (from Old French 'odor', ultimately from Latin 'odor' meaning a smell or scent) and 'sensor' (coined in the 20th century from Latin 'sensus', meaning perception or feeling, combined with the agent suffix '-or'). The Japanese transliteration 'kyūkaku-sensā' directly translates to 'olfactory sensor', combining 'kyūkaku' (sense of smell) with the katakana loanword 'sensā'.
