Learner notes
Memory Tip
记忆联想：signal 里藏着 sign（标记），把标记传出去就是“发信号”。
Context & Register
语域：neutral 常见场景：交通、日常沟通 signal 作动词时属于中性常用词，日常对话和书面语中都可使用。通常表示以手势、标志或设备等方式发出信号或表明意图；在较正式的文书或技术说明中也很自然，但如果强调非常随意的口头提醒，则不如 tell 或 let someone know 常用。
Grammar Note
In British English, the past and past participle are 'signalled' and the present participle is 'signalling'.
Pronunciation & Spelling
与 signal /ˈsɪɡnəl/ 押韵的常用词几乎没有，因为 /ɡnəl/ 结尾很罕见。注意：sign /saɪn/ 中 g 不发音且元音不同；single /ˈsɪŋɡəl/ 的发音为 /ŋɡəl/，不是 /ɡnəl/；final /ˈfaɪnəl/ 和 criminal /ˈkrɪmɪnəl/ 虽以 -al 结尾，但重读元音不同，均不押韵。signature /ˈsɪɡnətʃər/ 与 signal 共享 /sɪɡn/ 开头，但结尾不同。
