Towards a unified account of na in Akan

Grammatical accounts of na in Akan identify two different forms: nà with a low tone (LT-na) and ná with a high tone (HT-na). LT-na functions in two ways: as a focus marker or a conjunction, the latter of which can take a prefix and be realized as ɛna. While some scholars treat them as two different na’s, others point to a commonality between the two.HT-na has been analyzed as functioning as past and future tenses, and a logical connector. We argue that these three HT-na along with the two LT-na are subcategories of a super-category. We propose that the super-category is a non-tonal na (call it Root-na), with a common basic meaning which explains all five seemingly unrelated interpretations. Root-na links the na-clause with something in the common ground, i.e., to something that appeared in the previous context or is presupposed. It is spelled out as a LT-na or HT-na, depending on the kind of linking. LT-na marks discourse coherence relations such as focus and narrative-sequence, both of which are shown in the linguistics literature to be anaphoric. HT-na is an intensional marker which links times or possible worlds.
