邮递员在英语中被称为 "postal worker" 或 "mail carrier"。这个词的来源可能源于法语中的 "poste"，指的是邮递员所工作的邮政局。例句如下：

The postal worker delivered the package to my doorstep. (邮递员将包裹送到了我的门口。)

The mail carrier sorted the mail before putting it into the appropriate mailboxes. (邮递员在把邮件放入适当的邮箱之前先把它们分类。)

The postal worker is responsible for delivering mail to homes and businesses in a specific area. (邮递员负责将邮件送到某一特定地区的家庭和企业。)
