Memory Tip
联想：无人机(unmanned)里没有一个'man'（人）在驾驶，所以就是'无人的、无人操纵的'。
Context & Register
语域：neutral 常见场景：航空航天、军事、科技报道 ‘unmanned’ 通常用于较正式或技术性的场合，表示‘无人的、无人操纵的’；日常口语中表达‘无人驾驶的’时更常说 driverless 或 autonomous。
Pronunciation & Spelling
Unmanned /ənˈmænd/ ends with the sound /ænd/. It rhymes with manned, canned, planned, scanned, band, and hand. The words manned, canned, planned, and scanned also share the -anned spelling ending. Band and hand are spelled with -and instead. Watch out for lookalikes: maned /meɪnd/ (and unmaned /ʌnˈmeɪnd/) have one n and a long a, so they do not rhyme.
