??The oldest words in our lexicon (largest font in image) change through history slowly enough that they might have been recognized by people living 15,000 years ago or more, younger words (small font) would not. Our ancient shared speech is dominated in all languages by social relations: you, me (I), what we do, to whom, and has been throughout our history. Map credit: Mark Pagel and Andreea Claude
