espresso: [20] Etymologically, espresso is coffee that has been ‘pressed out’. The word comes from Italian caffè espresso, literally ‘pressed-out coffee’, which refers to the way in which the coffee is made by forcing pressurized steam or boiling water through the finely ground beans. Espresso is the past participle of esprimere ‘press out’, from Latin exprimere – which is also the source of English express.
