手动

• 병음: shǒu dòng
• 한자 분석: 手 = a pictograph of a hand; 动 = 重 + 力 (to move — applying force to something heavy; movement through physical effort)

뜻

수동; 손으로 조작하는

Directly contrasts with 自动 (automatic). Used across mechanical, digital, and procedural contexts: 手动挡 (manual transmission/gearbox), 手动对焦 (manual focus), 手动操作 (manual operation), 手动保存 (to save manually). In software and digital contexts, refers to user-initiated actions as opposed to automated processes. The term has become increasingly common as automation has expanded and the need to distinguish manual from automatic processes has grown.

올바른 표현

• 在精密制造中，保留手动操作是因极高精度要求，微米级装配仍难被自动化稳定复制。(In precision manufacturing, keeping manual operation is due to extremely high accuracy requirements; micron-level assembly is still hard for automation to reproduce reliably.)
• 云存储默认自动同步，但需要先审查文件的人可改用手动同步，避免敏感文件误上传。(Cloud storage defaults to automatic sync, but people who need to review files first can switch to manual sync to avoid accidentally uploading sensitive files.)

피해야 할 표현

• 手动 to mean laborious or difficult — it simply means 'done by hand / not automated'; do not use 手动 as an adjective implying difficulty or inconvenience; if the nuance is that something is cumbersome, use 繁琐 (tedious, cumbersome) or 费时费力 (time-consuming and laborious)
