““Finally, the Pirahã language is notoriously difficult because it lacks things that many other languages have, especially in the way that it puts sentences together. For example, the language has no comparatives, so I couldn’t find expressions like this is big/that is bigger. I couldn’t find color words—no simple words for red, green, blue, and so on, only descriptive phrases, like that is like blood for red or that is not ripe yet for green.””
