Three terms, three questions
Balts is used here for peoples associated with Baltic languages. Baltic languages names a branch of the Indo-European language family. Baltic states is the regional term for Lithuania, Latvia and Estonia. These meanings overlap, but are not interchangeable.[1]
A useful first question is therefore what a writer means by “Baltic”. A language relationship, a political border and a person’s identity require different evidence.
The language group and the region
Lithuanian and Latvian are the living languages at the centre of Baltic linguistic studies. Old Prussian belongs to the historical record of the group. Dini’s introduction distinguishes Baltic languages from all the languages spoken around the Baltic Sea.[1]
Estonian provides a clear regional comparison. The University of Tartu’s ESTTYP project places its study of Estonian alongside Southern Finnic varieties and describes contact with Baltic languages. A regional discussion can include Estonia without classifying Estonian as a Baltic language.[2][1]
Keep the distinction when searching for sources. A work about the Baltic states may cover a wider range of languages and communities than a work about Baltic linguistics.
Historical names need context
The historical Baltic-language record includes names such as Prussian, Curonian, Selonian and Semigallian. The surviving evidence is uneven, so a list of names is not a list of equally well-documented languages or communities.[1]
Before using a historical name, identify the period, the writer’s terminology and the evidence behind the classification. This introduction does not assign tribal borders, reconstruct populations or give dates for their origins.
Reading a claim about identity
For a historical account or a family-history record, ask:
- Who? Which person or community is actually named?
- When and where? Which period and geographical area does the evidence cover?
- What category? Is the record about language, citizenship, self-identification or ancestry?
- What source? Does the reference support that specific wording?
A description of language use is not, by itself, a record of someone’s citizenship or family ancestry. Keep the categories used by the source visible when paraphrasing it.
