'scentless' originates from the Middle English word 'scent,' combined with the suffix '-less,' where 'scent' meant 'a distinctive smell' and '-less' meant 'without.'

'scent' changed from the Old French word 'sentir,' which meant 'to feel or perceive,' and eventually became the modern English word 'scent.'

Initially, 'scent' meant 'to perceive by smell,' but over time it evolved into its current meaning of 'a distinctive smell.'
