choronym

Choronym (from 'region' or 'country' and 'name') is a linguistic term that designates a proper name of an individual region or a country. The study of regional and country names is known as choronymy, or choronymics. Since choronyms are a subclass of toponyms, choronymic studies represent a distinctive subfield of toponymic studies and belong to the wider field of onomastic studies.

Choronymic studies are primarily focused on questions related to the origin (etymology) and meanings (semantics) of choronyms. Since names of regions and countries have great historical, cultural, political and social significance, the field of choronymic studies is closely related to sociolinguistic and ethnolinguistic studies.
