Humans are the only species on the planet whose communication system exhibits enormous diversity. And linguistic diversity is crucial for understanding our capacity for language. There are over 7,000 languages spoken in the world today. These languages exhibit enormous diversity, from the number of distinctive sounds (there are languages with as few as 11 different sounds and as many as 118) to the vast range of possible word orders, structures and concepts that languages use to convey meaning. Every absolute that linguists have posited has been challenged, and linguists are busy debating if there is anything at all that is common to all languages in the world or anything at all that does not exist in the languages of the world. Sign languages show us that languages do not even need to be spoken. This diversity is evidence of the enormous flexibility and plasticity of the human brain and its capacity for communication. Studying diverse languages gives us invaluable insights into human cognition. But language diversity is at risk.
