This paper describes a phenomenon prevalent in South Central Tibeto-Burman languages, which we call multi-functional deictics (MFDs). Descriptively, MFDs are demonstratives that appear in multiple positions in the noun phrase, typically at the left edge and the right edge. They often co-occur and match in form, resulting in an apparent circumfix. MFDs are distinct from double definiteness or the reinforcer construction in Romance and Germanic languages, where a demonstrative co-occurs with a determiner or emphatic. In the case of MFDs, the two forms are both demonstratives, often identical. Although MFDs are prevalent in South Central Tibeto-Burman, even the most basic questions about MFDs remain to be answered, such as whether their core meaning derives from distance in space, evidentiality, or something else; and what syntactic structures result in the two distinct positions. We provide a range of hypotheses for these questions and outline what kinds of data are needed to test those hypotheses. Additionally, we find significant variation within South Central Tibeto-Burman in the specific properties of MFDs. More broadly, MFDs provide an important test case for noun phrase syntax that has complex interactions with other grammatical phenomena like case marking.
