The book Patterns in the Mind by Ray Jackendoff approaches the question of how language works. Language is perhaps the most unique aspect of humanity, as we are the only creatures to have the capacity for this type of communication. The book explores this facility of language, and what goes into the process of learning and becoming fluent in a language. The book questions what is specifically human about the ability to create and use language, and to what extent language is a result of nature versus nurture Jackendoff is very careful to differentiate between language and communication in this book: while many animals communicate, only humans have the complex grammar systems that constitute language.
