TK-421 (pronounced Teekay four two one) is the serial number of a character in a science fiction movie (and also my charming cat). What would be the most natural way to write this down?



Should anything be done with the letters?

  • T can correspond with any [ti] pinyin and K corresponds with any [kei] pinyin, you could theoretically come up with something like: 踢剋-四二一

  • The Chinese translation usually comes out to something like: 编号Tk421

  • You want to write it down instead of read it out? then TK-412 is OK. No Chinese character is needed.

TK-421, as a serial number, is ok in Chinese. But pronounce differently from English.
