It was a guidebook for an international auxiliary language, a kind of backup language, which could be used by people from different nations to communicate with each other.

它是一种国际辅助语言的指南，一种备用语言， 可供不同国家的人们用来相互交流。

However, it never quite became a universal auxiliary language, perhaps due to the rise in power of Britain and the United States after World War II, which cemented English's role as a de facto lingua franca.

然而， 它从未完全成为一种通用的辅助语言，这可能是由于二战后英国和美国实力的崛起，这巩固了英语作为事实上的通用语言的作用。
