A record of employees who are paid by a company, including how much money each person earns.

Payroll → The word is formed from "pay" (from Old French *paier*, meaning to pay) and "roll" (from Old French *rolle*, meaning a list or document). The term "payroll" refers to a list of employees and the amounts they are to be paid.
Think of a 'list' ('roll') of people who are 'paid' ('pay') — that's what payroll means.
