Shan, a Southwestern Tai language spoken in Myanmar, Thailand, and nearby countries, uses bare nouns to express both unique and anaphoric definiteness, a definiteness distinction identified by [15]. This novel data pattern from the author’s fieldwork can be analyzed by adding an anaphoric type shifter, \(\iota ^x\), to the available type shifting operations defined by [6] and [7]. Otherwise, the data from Shan fit well with predictions from a type shifting analysis as laid out by [8]. Additionally, this paper demonstrates that the consistency test [7] is not sufficient to determine what counts as a definite determiner for a language.
