'adjustable' originates from the Latin word 'adjustare,' meaning 'to make right or fit,' and 'temperature' comes from the Latin 'temperatura,' meaning 'a moderate condition.'

'Adjustable' evolved from the Old French 'ajuster,' and 'temperature' from the Old French 'temperature.'

Initially, 'adjustable' meant 'to make right,' and 'temperature' referred to 'moderate condition,' evolving to mean 'capable of being set to a desired temperature.'
