'inhaler' originates from the Latin word 'inhalare,' where 'in-' meant 'into' and 'halare' meant 'to breathe.'

'inhalare' transformed into the French word 'inhaler,' and eventually became the modern English word 'inhaler.'

Initially, it meant 'to breathe into,' but over time it evolved into its current meaning of 'a device for inhaling medication.'
