book（书）+ maker（制造者）→ 制书人；又因赌场用“book”记录赌注，故也指赌注登记经纪人。
语域：neutral 常见场景：horse racing、sports betting、betting shops 该词通常指赌注登记经营者（俗称 bookie），多用于赛马、体育博彩等场景；语体中性。若指著作者或编书人，则属于正式用法，较少见。
这些词与 bookmaker 并不整词押韵：真正的整词押韵需要以 /ʊkmeɪkə/ 结尾。book、look、cook、hook 的元音和尾辅音与 bookmaker 重读的第一音节 /bʊk/ 相同；maker、shoemaker 拼写与 -maker 部分相同，但重音不在该部分上。注意：-ook 中的 oo 读 /ʊ/（如 book /bʊk/），不是 /uː/。
