Merriam-Webster's Word of the Day is
perquisite
pronounced PER-kwuh-zut
a noun meaning something extra that someone receives in addition to regular pay for doing a job
or, as listed in the dictionary,
1 : a privilege, gain, or profit incidental to regular salary or wages

Perquisite comes from the Latin word perquirere (the prefix per-, meaning “thoroughly” and the verb quaerere, meaning “to ask” or “to seek.”) Instead of perquisite, most people use perk, as in job perks, a word which was formed by shortening and altering perquisite.
