'accurate' originates from Latin, specifically the word 'accuratus,' where 'ad-' meant 'toward' and 'cura' meant 'care.' 'Update' comes from the combination of 'up' and 'date,' meaning to bring something to the present time.

'accuratus' transformed into the French word 'accurate,' and eventually became the modern English word 'accurate.' 'Update' was formed in modern English by combining 'up' and 'date.'

Initially, 'accurate' meant 'done with care,' but over time it evolved into its current meaning of 'precise and correct.' 'Update' has maintained its meaning of bringing something to the present time.
