The sapir whorf hypothesis

Language is relative. Your perspective is influenced by the language you speak. And language is more than words.

We use body language more than speaking. Pointing is rude in the US but in some countries it’s no problem. The OK sign is rude in Brazil and it’s an obscene gesture in parts of the Middle East. There are different sign language varieties. Chinese signing is too different than American signing to be understood by those who know it. Each language evolved to fit their culture.

Language is an ever evolving system of communication that reflects the cultures of the people who use it. If a designer wants to design for a group, like a niche, they have to learn the language.
