记法：transition 与 tradition 只差一个字母，传统（tradition）需经历过渡（transition）才能改变。
语域：mixed 常见场景：职场与组织变革、学术或正式写作、性别认同话题 作为动词时，transition 多用于较正式或书面语境，如职业发展、组织变革；在谈论性别过渡时也比较常见。日常口语中有时会说成 switch 或 move on，但 transition 并非生僻词。整体风格偏中性，可根据具体场合选用。
这些词都与 transition 的重读部分 /ˈzɪʃən/ 押韵，重读元音均为 /ɪ/。注意不要仅凭拼写判断：如 nation /ˈneɪʃən/ 和 question /ˈkwestʃən/ 虽也以 -tion 结尾，但元音不同，不押韵。
