protoonomastic

Protoonomastic is an academic term used in linguistics and onomastics to describe the study of the origins and historical development of proper names at the proto-language stage. It focuses on how personal names (anthroponyms), family names, and place names (toponyms) can be reconstructed in a proto-language and how their reflexes arise across descendant languages. The aim is to understand not only the etymology of individual names but also the naming practices and linguistic processes that produce toponyms and ethnonyms in early linguistic communities.

Methods include the comparative method to establish cognate sets across languages, internal reconstruction to infer unrevealed proto-forms, and semantic analysis to trace shifts in meaning. Researchers draw on inscriptions, ancient texts, ethnonyms, and toponyms preserved in later languages to ground hypotheses about proto-forms and their semantic fields. Protoonomastic work often addresses issues such as the formation of names from common nouns, kinship terms, occupations, geographical features, or ethnonyms, and how these elements migrate or transform through sound changes and semantic drift.

Applications of protoonomastics include shedding light on historical migrations, cultural contact, and the social meaning of names in ancient communities. It is a specialized subfield within onomastics, complementing broader studies of personal names and place names by emphasizing the earliest, reconstructible layers of naming systems.
