Lending money at excessive interest. Originally it meant lending at any interest at all — the word narrowed as the practice became respectable.
What it really means
Usury now means lending money at a punishing rate. For most of its life in English it meant something much broader: lending money at interest at all.
The word arrives around 1300 as usurie, through French from Medieval Latin, and behind it is Latin usura — payment for the use of money. That comes from uti, to use, which also gives English use. So the charge is, etymologically, nothing more sinister than a fee for the using: you had my money for a year, and the fee is what the having cost.
The moral weight came from elsewhere. Lending at interest was condemned outright across medieval Christian Europe, and the word carried that condemnation with it. By the mid-15th century the record shows the narrower sense — the premium paid for the use of money, especially exorbitant interest.
That narrowing is the whole story of the word, and it is a pattern worth recognising. A word that condemns an entire practice cannot survive unchanged once the practice becomes ordinary. Either it loses its sting or it retreats to the extremes. Usury retreated. Interest became banking, respectable and universal, and the old accusing word was left guarding the far end of the scale, where it still sits in the statute books as the name for a legal limit.
What it no longer does is what it was built for: describing what everybody's mortgage is.
Where it comes from
Usury and use are the same root: the charge is literally a fee for the using.
Myths & misconceptions
Usury has always meant charging too much interest.
It first meant charging interest at all. The narrowing to 'excessive' interest follows the practice becoming normal: once ordinary lending was respectable, the old condemning word had to be reserved for the extreme cases.
Usury is a religious word with no legal meaning.
Both. Many jurisdictions still set usury limits — legal caps on the interest a lender may charge — and the word survives in those statutes long after it left ordinary speech.

- Euphemismwhat happened to the vocabulary around it: the blunt word was retired and replaced with softer ones.
Questions people ask
- What does usury mean?
- Lending money at unreasonably high interest. In its earliest English use, around 1300, it meant lending at interest of any size.
- Why did usury stop meaning all interest?
- Because charging interest became ordinary commerce. A word that condemned the whole practice could not survive unchanged once the practice was respectable, so it narrowed to the cases still considered indefensible.
