This article discusses in detail computational morphology with examples from various languages. It deals with the processing of words in both their graphemic, i.e. written, and their phonemic, i.e. spoken form. It has a wide range of practical applications such as spelling correction or automated hyphenation. It further seeks the fact that these tasks may seem simple to a human but they pose hard problems to a computer program. This article provides insights into why this is so and what techniques are available to tackle these tasks. It discusses the sort of information that is expressed by morphology and differs widely between languages and looks at the constraints involved in morphotactics. It is responsible for governing the rules for the combination of morphs into larger entities. It concludes with an outline of finite-state morphology and alternative formalisms.

Keywords: computational morphology; automated hyphenation; morphotactics; finite-state morphology; formalisms
