Relational nouns or relator nouns are a class of words used in many languages. They are characterized as functioning syntactically as nouns, although they convey the meaning for which other languages use adpositions (i.e. prepositions and postpositions). In Central America, the use of relational nouns constitutes an areal feature of the Mesoamerican Linguistic Area, including the Mayan languages, Mixe–Zoquean languages, and Oto-Manguean languages.[1] Relational nouns are also widespread in South-East Asia (e.g. Vietnamese, Thai), East Asia (e.g. Mandarin Chinese, Japanese, Tibetan), the Munda languages of South Asia (e.g. Sora), Micronesian languages and in Turkish.
