'acclimature' originates from French, specifically the word 'acclimater,' where 'ac-' meant 'to' and 'climat' meant 'climate.'

'acclimater' transformed into the English word 'acclimate,' and eventually became the modern English word 'acclimature.'

Initially, it meant 'to adapt to a climate,' but over time it evolved into its current meaning of 'the process of becoming accustomed to a new climate or environment.'
