intern 含 in＋tern，想象实习生“在(in)里面”轮转学习；作动词“拘留”时，也可联想被关在“里面”。
语域：neutral 常见场景：企业/公司实习、医院/医疗机构 作名词时通常指在公司或机构实习的学生或刚毕业者，也可在医院语境中指实习医师；多用于职场和校园场景，语气中性，正式与日常交流中都比较常见。
burn、turn、learn、yearn、fern 都与 intern 的重读部分 /təːn/ 押韵（都读 /əːn/），拼写分别是 -urn、-earn、-ern。注意形近词 internet (/ˈɪntənet/) 虽以 intern- 开头，但发音完全不同；internal (/ɪnˈtəːnəl/) 也易混淆，但多一个 /əl/ 音节，不完全押韵。
