Origins
The word 'espresso' entered English around 1945, borrowed from Italian 'caffè espresso,' literally 'pressed-out coffee.' The Italian 'espresso' is the past participle of 'esprimere' (to press out, to squeeze out, to express), which descends from Latin 'exprimere,' a compound of the prefix 'ex-' (out, out of) and the verb 'premere' (to press, to squeeze). The Latin 'premere' traces to PIE *per- (to strike), a root that also produced, through Latin, the enormous English family of 'press,' 'compress,' 'depress,' 'express,' 'impress,' 'oppress,' 'repress,' 'suppress,' and 'print' (from Old French 'preinte,' an impression or stamp, from Latin 'premere').
The name 'espresso' refers to the method of preparation: hot water is forced under pressure through finely ground, tightly packed coffee, extracting a concentrated brew. The first espresso machines were developed in Italy in the late nineteenth and early twentieth centuries. Angelo Moriondo of Turin patented an early steam-driven coffee machine in 1884. Luigi Bezzera patented improvements in 1901, and Desiderio Pavoni began manufacturing commercial machines in 1905. These early machines used steam pressure, which often scalded the coffee. The modern espresso machine, using a piston to generate higher pressure at lower temperatures, was invented by Achille Gaggia in 1948 and produced the thick, crema-topped espresso familiar today.
The etymology of 'espresso' is frequently misunderstood in English, where the common misspelling 'expresso' reflects a folk-etymological association with 'express' in the sense of 'fast.' This confusion is compounded by the fact that Italian does have a word 'espresso' meaning 'express, fast' — used in 'treno espresso' (express train) — which derives from the same Latin 'exprimere' but through a different semantic pathway (the idea of something 'sent out' directly, without stops). However, 'caffè espresso' uses 'espresso' in its literal participle sense of 'pressed out, extracted,' not in its 'fast' sense. The coffee is named for its method of extraction, not for the speed of its preparation.
Development
English borrowed 'espresso' after World War II, as American soldiers returning from Italy brought back a taste for Italian coffee. The word appeared in English-language publications from 1945 onward. The spread of Italian-style espresso bars in Britain in the 1950s (notably the Gaggia-equipped coffeehouses of Soho) and the later global expansion of espresso culture through chains like Starbucks (founded 1971, refocused on espresso in 1987) made the word ubiquitous.
The derivatives and compounds of 'espresso' in English are numerous: 'espresso machine,' 'espresso bar,' 'double espresso,' 'espresso shot,' 'espresso-based' (used to describe cappuccinos, lattes, and other drinks built on an espresso foundation). The Italian coffee vocabulary borrowed into English alongside 'espresso' includes 'cappuccino' (from the colour of the Capuchin monks' robes), 'latte' (Italian for 'milk'), 'macchiato' (stained or spotted), 'ristretto' (restricted, shortened), and 'lungo' (long). This Italian stratum in the English coffee lexicon mirrors the French dominance of wine and fine-dining vocabulary — each cuisine exports its terminology along with its products.
The cultural significance of 'espresso' extends beyond the beverage. In English, 'espresso' has become a shorthand for Italian café culture, urban sophistication, and the rituals of coffee consumption. The espresso bar — standing at a counter, drinking a small, intense shot — represents a European approach to coffee that contrasts with the American tradition of large, diluted cups consumed while working. The word thus carries cultural associations beyond its literal meaning, functioning as a marker of cosmopolitan taste and caffeinated intensity.
