'maintain' originates from Latin, specifically the word 'manutenere,' where 'manu-' meant 'hand' and 'tenere' meant 'to hold.'

'manutenere' transformed into the Old French word 'maintenir,' and eventually became the modern English word 'maintain' through Middle English.

Initially, it meant 'to hold in the hand,' but over time it evolved into its current meaning of 'to keep in good condition.'
