The original Polish name for "witcher" is wiedźmin. The English translation preferred by Andrzej Sapkowski was initially "hexer." "Hexer" was the name used in the international version of the film adaptation. "Hexe" and "hexer" are the German terms for "witch" and "warlock." However, CD Projekt chose to translate "hexer" literally to "witcher" in The Witcher computer game. Danusia Stok subsequently used this version in her translation of the book The Last Wish. Sapkowski himself used the term "witcher" in his own book Historia i Fantastyka. Michael Kandel used "spellmaker" in his translation of the story "Wiedźmin" in 2010.
Alternatively, the word warlock has been used informally in English translations, while "witcher," being a neologism in English (as wiedźmin is in Polish), arguably describes the uniqueness of Geralt's profession better.

说到翻译的话，欧陆那边的本地化不清楚，像中国日本之类的都是拿英文版作底本来做的
英翻主力一个在美国长大的波兰人，一个长期居留波兰的美国人，都是在CD Projekt社内工作，有什么和脚本那边直接交流
你看太空战士还不是直接沿用到了12吗？
