commission fee
佣 centers on a fee paid for a service or transaction, specifically a commission fee.
佣 combines 亻 (person) with 用 (use), suggesting a person used for a service in exchange for a fee. The exact historical development is uncertain.
A person 亻 is used 用 for a task and receives a commission fee in return.
For ヨウ, imagine a person earning a commission by yelling 'Yo!' to attract customers: Yo -> ヨウ.
