means The total money a business or government takes in from its activities before any expenses are subtracted.

from From Old French 'revenue,' the past participle of 'revenir' — 'to return, to come back' — built from Latin 're-' (back) and 'venire' (to come). The literal idea is money that 'comes back' to you, the income that returns from what you've put out into the world. The same Latin 'venire' fathered a crowd of arrivals: 'avenue' (the way you come up), 'convene' (to come together), and 'venue' (the place things come to).
