Learner notes
Memory Tip
联想：suction 以 suck（吸）开头，加名词后缀 -tion，即“吸力”——像吸尘器那样把东西吸过来。
Context & Register
语域：neutral 常见场景：物理/工程、日常器具、医疗 “suction”作名词时通常指因压力差产生的吸力，多用于物理、工程或日常器具（如吸尘器、抽水泵）等语境，也可见于医疗场景；口语和书面语都自然，属于中性用词。
Pronunciation & Spelling
这些词的重读元音都是 /ʌ/，后面都接 /kʃən/，所以与 suction 押韵。注意不要和拼写相近的 function /ˈfʌŋkʃən/、junction /ˈdʒʌŋkʃən/ 混淆，那两个词中发的是 /ŋkʃən/。
