Formalization of the Quechua Morphology

I present a method to formalize the morphology of Quechua nouns, verbs, and other Part Of Speech (POS) categories to develop Natural Language Processing (NLP) applications. First, I constructed an electronic corpus comprising several digitalized texts and electronic dictionaries. After a detailed inventory of all Quechua suffixes, I classified them into specific sets corresponding to their POS category. Next, I formalized their grammatical behavior separately, using elementary matrices. The resulting tables describe valid combinations of two, three, and four suffixes. Finally, I formalized the inflection and derivation of each POS category.
