Emolument

Something you use to moisturize your skin.

Er, that's emollient.

An emolument is a personal benefit someone derives from an office or position. If you get a salary from your employer, that's technically an emolument. But if you're in a job interview and they start talking about how your emolument for the position is $18.50 an hour...you've found a weirdly pretentious potential employer.

The word "emolument" is most famous for appearing in the U.S. Constitution, in the so-called "emoluments clause." This section bans federal office holders from receiving a benefit (or, as James Madison would call it, an emolument) from a foreign country...unless, of course, Congress gives the okay first.
