记忆联想：in-（无）+ test（遗嘱，来自testament）+ -acy（状态），即未留遗嘱的状态。
语域：formal 常见场景：法律文书、遗嘱与继承讨论、法庭与律师语境 intestacy 多用于正式或法律语境，表示未留有效遗嘱而去世的状态；日常口语中较少见，通常出现在遗嘱、继承等法律文件中。
这些词都与 intestacy 以 -acy 结尾，拼写模式相似，但重读元音及后续辅音不同，并不相互押韵。intestacy 的重读元音为 /ɛ/（inˈtestəsi），而 privacy 的重读元音为 /aɪ/，accuracy 为 /æ/，因此只是拼写上的形似词。常见词中没有与 intestacy 完全押韵的词；真正同韵的 testacy（/ˈtɛstəsi/）很罕见，这里不列。
