Ergative case? Absolutive case?? Allocutive case??? Basque is showing me the limits of my English vocabulary.
The purpose of examining the grammar of a language is to be able to describe its salient features and to demonstrate how the language behaves. This is the bare minimal set of grammatical elements that will be investigated for each language.
Originally I was looking for a sequence of sentences that, in the fewest number of sentences possible, provides the barest building blocks for communicating in a language.
Full disclosure: Developing a concise minimal grammar set has been tougher than I thought it would be. It's a struggle between two opposing forces: the desire to keep the minimal grammar set down to bare necessities versus the urge to be exhaustive and thorough.
