 From a linguistic point of view disjunction is a kind of coordination, where coordination refers to syntactic constructions in which two or more units of the same type are combined into a larger unit and still have the same semantic relations with other surrounding elements (Haspelmath 2007). An open question is whether disjunctive coordination is a universal that can be found in all languages. All languages appear to possess coordination constructions of some kind, but not all languages seem to have explicit coordinators like and and or. For example, Maricopa (a Yuman language of Arizona described by Gill 1991) and Dyribal (an Australian Aboriginal language described by Dixon 1972) seem to lack explicit coordination structures, so in these languages there is no word corresponding to or (see also Winter 1995). This does not necessarily mean however that these languages lack a way to express disjunctive meanings. Maricopa and Dyribal appear to be able to convey “\(A\) or \(B\)”, without explicit disjunctive coordinator, by adding a suffix/particle expressing uncertainty to the main verb.
