I keep seeing the word "perks" to describe special privileges, such as: "A free parking space is one of the perks of the job." It should be perqs, as in "perquisites":
Etymology: Middle English, property acquired by means other than inheritance, from Medieval Latin perquisitum, from neuter of perquisitus, past participle of perquirere to purchase, acquire, from Latin, to search for thoroughly, from per- thoroughly + quaerere to seek
1 : a privilege, gain, or profit incidental to regular salary or wages; especially : one expected or promised
2 : GRATUITY, TIP
3 : something held or claimed as an exclusive right or possession
