The oscar-winning movie Arrival has prompted some new interest the the Sapir-Whorf hypothesis that language constrains or enables certain abstract concepts. The idea that an alien language can rewire the brain's way of thinking about time is central to the movie.
One of the ideas in the hypothesis is that some languages enable much more nuanced discussion on a topic than other as they contain more words related to the idea. For example, Wikipedia records that:
One of Whorf's examples was the supposedly large number of words for 'snow' in the Inuit language
This appears to be the origin of a very widely repeated meme that eskimos (the Inuit at least) have hundreds of words for one of the commonest ingredients of their environment.
But the idea is controversial. Is it true?
