In our last lecture, I was talking about language as part of our semiotic system.

上次我们讲到，语言是号系部分。

Whoever thought that a book about " hypographic semiotics" could be so absorbing?

能想到本关于“亚号学”书会如此有趣？

I need your opinion on a matter of semiotics. I'm sorry?

我需要号学方面帮助。什么？

Semiotics. The study of signs and symbols. It's a branch of philosophy related to linguistics.

号学，研究号和象征，是语言学基本理论分支。
