Abstract
There is increasing recognition in typology that linguistic categories are language-specific and not universal, increasing the need for explicitness in language descriptions. In light of this development, I argue in this paper that preexisting labels and descriptions for a set of subject-marking TAM prefixes in Eleme do not adequately characterise the distribution and use of these forms, which is conditioned by the complex interaction of person and number features, Aktionsart, epistemic modality and information structure. In response to the challenges raised by these data, I argue that when multiple analytical perspectives are required to understand the function of a grammatical form, fine-grained quantitative analyses with description give a complex but useful basis on which to compare languages.
