IPA: /ˈpɜːrkɪzɪt/
KK: /ˈpɜrkwɪzɪt/
A benefit or privilege that comes with a job or position, often in addition to regular pay.
Many employees enjoy health insurance as a perquisite of their job.
Perquisite is formed from "per-" (meaning through) and "quisitum" (from "quaerere", meaning to seek or acquire). The term originally referred to something acquired through one's position or office, often as a benefit or privilege.
Think of 'seeking' ('quaerere') something 'through' ('per-') your position — that's why a perquisite is a benefit you gain from your role.
