For those interested, Michael Aubrey has uploaded his Master’s thesis on the Greek perfect to Academia.edu. Here is the abstract:
This thesis attempts to expand the theoretical and methodological basis for operators within Role and Reference Grammar for purposes of language description, using the Greek perfect as a test case. This requires first examining the current theoretical and methodological approach to tense and aspect in RRG and its strengths and weaknesses. Here I demonstrate that while some areas of RRG have a well-developed and robust set of theoretical and descriptive tools for language description, operators such as tense and aspect are distinctly lacking in this regard. To that end, I propose a model for tense and aspect operators that attempts to fill in the gaps that exist in RRG while also maintaining the integrity and spirit of the linguistic theory. This involves three steps. I begin with a survey of the broader typological literature on tense and aspect in order to establish a set of morphosyntactic tests for the evaluation and categorization of operators. This is followed by an application of the proposed morphosyntactic tests to a particular grammatical problem: the Greek Perfect in order to evaluate the effectiveness of the tests. I then concluded with a synthetic model for tense and aspect operators that both satisfies the theoretical and typological claims of the broader literature and also validates the existing structure of the Role and Reference Grammar framework, thereby furthering the goals of RRG as a useful theoretical model for language description.
