Memory Tip
overrun = over（超过）+ run（跑）: 跑过头就是超出量；飞机跑过头需要跑道端安全区；冰淇淋跑过头注入空气，体积膨胀。
Context & Register
语域：neutral 常见场景：project status reports、budget audits、construction contracts 该名词义项（超出量、超额）通常用于项目、预算等正式或半正式场合，如 cost overrun（成本超支）、schedule overrun（进度超限），多出现在报告、审计或媒体新闻中；日常口语较少直接用 overrun，更常说 go over budget。
Pronunciation & Spelling
这些单词都与 overrun 的尾音节 /rʌn/ 押韵（重读元音 /ʌ/ + 辅音 /n/）。注意 one 的拼写与发音不一致；overrun 虽然以 run 结尾，但整体读音为 /ˌəʊvəˈrʌn/，请勿与 overdue（/ˌəʊvəˈdjuː/）等词混淆。
