Memory Tip
把 knock（敲）和 out（出）连起来：想象一拳把对手“敲出”赛场，瞬间倒地，就是击倒（KO）或淘汰。
Context & Register
语域：neutral 常见场景：boxing、sports commentary 在拳击语境中，knockout 通常用于中性场合，体育报道和日常谈论比赛都比较常见；正式文体中可选用 technical knockout 这类更完整的说法。
Pronunciation & Spelling
out、shout、about、without、doubt 都与 knockout 结尾的 /aʊt/ 押韵；doubt 中的 b 不发音。knock 拼写与 knockout 前半相同，但读 /nɒk/，不与 -out 押韵。
