注意:真正与 phosphor /ˈfɔsfə/ 完全押韵的常用词很少,下列词都不是完全押韵。fossil /ˈfɒsəl/ 与 phosphorus /ˈfɒsfərəs/ 在前部的 /fɒs/ 上相似,其中 phosphorus 完整包含 phosphor 的拼写和读音,只是后面多出 /əs/。gopher /ˈɡəʊfə/ 的结尾 -pher 与 phosphor 的 -phor 读音相同,都是 /fə/,但重音和元音不同,故不押韵。metaphor /ˈmetəfɔː/ 与 semaphore /ˈseməfɔː/ 是拼写上的相似物,-phor/-phore 实际读 /fɔː/,不是 phosphor 末尾的 /fə/。sphinx /sfɪŋks/ 的 sph 在拼写和读音上与 phosphor 的 ph- 相关(都读作 /sf/ 或 /f/),但整体读音差别大。
