An introductory textbook on language and linguistics. It provides a chapter on each of the more established areas in linguistics such as lexicology, morphology, syntax, phonetics and phonology, historical linguistics, and language typology and on some of the newer areas such as cross-cultural semantics, pragmatics, text linguistics and contrastive linguistics. In each of these areas language is explored as part of a cognitive system comprising perception, emotion, categorisation, abstraction processes, and reasoning. All these cognitive abilities may interact with language and be influenced by language. Thus the study of language in a sense becomes the study of the way we express and exchange ideas and thoughts.
