把 rodent 拆成 rod+ent，想象老鼠抱着木棍（rod）啃，啮齿动物门牙不断长，靠啃咬磨牙。
Context & Register
语域：neutral 常见场景：日常对话、科普文章、生物学文献 rodent 作名词时是中性常用词，日常聊到老鼠、松鼠等动物时会出现，正式科研文章里也通用；语气不俚俗，也不显生硬。
Pronunciation & Spelling
没有常见的与 /ˈroʊdənt/ 押韵的词。accident、resident、president 彼此押韵（结尾 /ɪdənt/），trident 读 /ˈtraɪdənt/，dent 读 /dɛnt/，它们都与 rodent 的 /roʊdənt/ 不同。rod 的前三个字母虽相同，但读音为 /rɑːd/，也不是 /roʊ/。
