Borrowed from Italian espresso, from caffè espresso (“pressed-out coffee”), form of esprimere (“to press out”), from Latin exprimere, from ex- (“out”) + primere (“to press”).
Some sources derive the term from “expressly (‘individually, directly’) made for the customer”, or as “fast” (Italian espresso also meaning “fast”, as in English express (“fast”)) but these are not widely credited. The original term for modern espresso (coffee extracted under pressure) was cream coffee, from Italian caffè crema (variant: crema caffè), due to the crema, and was seen on early Gaggia machines, but this term is no longer used.
espresso (countable and uncountable, plural espressos or espressi)

ESPRESSO (Echelle SPectrograph for Rocky Exoplanet- and Stable Spectroscopic Observations) is a new-generation, high-resolution, fiber-fed and cross-dispersed echelle spectrograph (R = 140’000) for the visible wavelength range (350 nm – 720 nm), for ESO's VLT. Its main feature is the spectroscopic stability and the radial velocity precision. With incredible 'spectroscopic' precision, it will be able to detect Earth-like planets. For example, our Earth induces a radial-velocity variation of 9 cm/s on our Sun.
