Following the Mapuche grammar by Smeets, this article describes the main morphophonological aspects of Mapudüngun, explaining what triggers them and the contexts where they arise. We present a computational approach producing a finite state morphological analyser (and generator) capable of classifying and appropriately tagging all the components (roots and suffixes) that interact in a Mapuche word form. The bulk of the article focuses on presenting details about the morphology of Mapudüngun verb and its formalisation using FOMA. A system evaluation process and its results are also present in this article.
