So what does it mean that some languages have words for things that other languages don't? Anything? (I'm not talking about specific environmental words here - it figures that English would have a word for oak & a tropical language would have words for different kinds of orchids.) Do languages have a mood?
Also (forgive my ignorance), what is the weak Sapir-Whorf hypothesis? Does that exist? (& if there's strong & weak, is there gravitic & electromagnetical? Sorry, couldn't resist..)
