various grammatical functions of the verb are communicated morphologically by the selection of a given verbal ending from a system of choices (e.g., singularity vs. plurality, first person vs. second person, or perfective vs. imperfective aspect). This suggests that an important linguistic principle for interpreting the Greek verbal system (or any part of the grammatical system) is that “meaning implies choice,” as the grammar can be seen as a series of meaningful choices within the language system.
