Abstract

The first version of the Basque Constraint Grammar (BCG) was developed in 1995–1997 by two linguists (Aduriz et al., 1997) based on the Constraint Grammar theory of Karlsson (1990; Karlsson et al. (1995). Since then, it has undergone many changes, by many grammarians. During the two decades of development, the Basque morphological analyser has also been updated several times, and not always synchronised with the CG. As a result, the Basque grammar needs serious attention.

In the present paper, we describe the ongoing process of cleaning up the Basque grammar. We use a variety of tools and methods, ranging from simple string replacements to SAT-based symbolic evaluation, introduced in Listenmaa and Claessen (2016), and grammar tuning by Bick (2013). We present our experiences in combining all these tools, along with a few modest additions to the simpler end of the scale.
