Learner notes
Memory Tip
联想：使士兵因伤病变成“invalid（伤残者）”，从而被迫退役、离岗。记住重音在前，读作/ˈɪnvələd/。
Context & Register
语域：formal 常见场景：military discharge paperwork、formal/legal documents 动词 invalid 比较罕见，多用于正式书面语，尤其常见于军队退役或公务文书等语境；日常口语中通常较少直接说这个词，而更常用 make invalid 或 invalidate 表示“使无效”。
Pronunciation & Spelling
这些词拼写都含 -id，但读音与 invalid /ˈɪnvələd/ 并不押韵：valid /ˈvælɪd/、squalid /ˈskwɒlɪd/ 等以 -alid 结尾的词重音在首音节且元音不同；vivid、solid、timid 只是共享 -id 拼写。因此本组没有真正的同韵词。
