Licensed
“Licensed” 是 “license” 的过去分词，作形容词表示持有官方执照或许可的。常见于 “licensed driver”（持证司机）、“licensed software”（正版授权软件）等搭配。
- “Only licensed contractors can do electrical work here.” (此处只有持证承包商才能做电力工程。)
- “The bar is licensed to sell wine and beer.” (该酒吧获准销售葡萄酒和啤酒。)
- “She became a licensed nurse after passing the exam.” (通过考试后，她成为注册护士。)
“License” 来自拉丁语 “licentia”，由 “licere”（被允许）派生，核心含义是获得官方准许。
词根 “licens-” 与许可相关；动词后缀 “-e” 构成 “license”；“-ed” 表示已获许可的状态。
英美常用 “fully licensed” 强调资质齐全；软件领域区分 “licensed copy”（正版）与盗版；餐饮 “licensed premises” 指有售酒许可的场所。
- 动词: license（美式）/ licence（英式名词）
- 名词: license, licensee
- 固定搭配: “licensed driver” (持证司机), “fully licensed” (完全持证), “licensed product” (授权产品)
“license” 许可证 + “-ed” 已持证——licensed 就是有执照、获批准的。
“The licensed electrician inspected the wiring and issued a safety certificate the same day.” (持证电工检查了线路，当天就签发了安全证书。)
