/ˈrɛvənjuː/
[noun] The money that a government, company, or organisation receives regularly, especially from taxes, sales, or services. It is the total income coming in before any costs are taken away.
Revenue literally means 'that which has come back' — as if money is a traveller returning home to your pocket.
The story of 'revenue' begins in Latin, with the verb 'venire', meaning 'to come'. This was one of the most well-travelled verbs in the entire Latin language, and it set off on a journey of its own through the centuries, picking up prefixes and new meanings along the way. When the prefix 're-' — meaning 'back' or 'again' — was attached, the compound verb 'revenire' was born, carrying the meaning 'to come back' or 'to return'.
As Latin evolved into the Romance languages of medieval Europe, 'revenire' passed into Old French as 'revenir', still meaning 'to return' or 'to come back'. From this verb, Old French speakers created a noun form, 'revenue', the past participle used as a noun, which literally described 'that which has returned' or 'a return'. In the world of medieval finance, this was a natural and elegant way to describe income — money that comes back to you after it has gone out into the world through trade, rents, and taxes.
The word crossed the English Channel in the 15th century, carried along with much of the French administrative and financial vocabulary that flooded into English after the Norman Conquest of 1066. English at this time was borrowing heavily from French for matters of governance, law, and commerce, and 'revenue' fit perfectly into this category. Early English uses referred specifically to the income of a monarch or noble landlord — the money flowing back from tenants, estates, and royal levies.
Over time, the word broadened considerably. What began as a term for aristocratic and royal income expanded to describe the financial returns of any government, then later of businesses and institutions of all kinds. The older sense of literal physical 'return' faded away, leaving behind only the financial meaning. Interestingly, the French word 'revenu' still exists today with exactly the same meaning — income — showing just how directly English borrowed the term without significant alteration.
The Latin root 'venire' also gave English a remarkable family of related words, each carrying a trace of the idea of 'coming'. Through Latin 'adventus' ('a coming to') came 'advent'; through Old French 'avenir' came 'avenue', originally a road along which one approaches or arrives. 'Event' came via Latin 'eventus', meaning 'an outcome' or 'that which comes out'. Even 'convention' travels back to 'venire', through Latin 'convenire' ('to come together') → Old French 'convention' → English 'convention'. Revenue, then, is not just a financial term — it is a quiet reminder that money, like a traveller, is always imagined as something in motion, going out and coming back.
