Other forms: expenses
An expense is money going out, one of the things you have to pay for. Rent, the train ticket, the boiler that broke in February.
In the singular it is the money itself: at great expense, spare no expense, a holiday not worth the expense. The plural is a different animal. Expenses is money you spend doing your job that your employer pays back, so people put in an expenses claim and talk about a trip being on expenses. The phrase to watch is at the expense of, which means something else was damaged to buy it: he built the business at the expense of his health. And a joke at your expense is a joke with you as the target.

Expense came through Middle English and Anglo-Norman from Latin expensa, the noun formed on expendo, the same Latin verb that gives English expend. Behind that stands a Proto-Indo-European root, (s)pend-, about paying out. Money leaving your hands has been the whole idea from the start.
