TL;DR

This paper investigates the lexical categories of Mapud"ungun roots to improve a morphological analysis system and clarify linguistic uncertainties in the language.

Contribution

It provides a lexical category classification of Mapud"ungun roots, supporting computational analysis and linguistic understanding.

Findings

Verified lexical categories of roots used in the morphological system.

Results directly integrated into the computational analyser.

Aims to clarify uncertainties about lexical categories in Mapud"ungun.

Abstract

After developing a computational system for morphological analysis of the Mapuche language, and evaluating it with texts from various authors and styles, it became necessary to verify the linguistic assumptions of the source used as the basis for implementing this tool. In the present work, the primary focus is on the lexical category classification of Mapud\"ungun roots recognised as verbal in the source utilised for the development of the morphological analysis system. The results of this lexical category revision directly benefit the computational analyser, as they are implemented as soon as they are verified. Additionally, it is hoped that these results will help clarify some uncertainties about lexical categories in the Mapuche language. This work addresses a preliminary task to identify the valency of true verbal roots, the results of which will be presented in a subsequent work that complements this article.
