'pressure-gauge' originates from the combination of 'pressure,' from Latin 'pressura,' meaning 'action of pressing,' and 'gauge,' from Old French 'jauger,' meaning 'to measure.'

'pressure-gauge' evolved from the Old French word 'jauger' and the Latin word 'pressura,' eventually becoming the modern English term 'pressure-gauge.'

Initially, it meant 'to measure pressure,' and this meaning has largely remained the same in modern usage.
