"stratum"の定義と意味

What is a "stratum"?

In linguistics, a stratum refers to a layer or level within a language that represents a specific historical, social, or linguistic influence. Strata can arise from various sources, such as contact with other languages, social class variations, or regional dialects. Each stratum contributes different vocabulary, grammar, or pronunciation features to the overall language, reflecting its evolution and development over time. For example, a language may have layers from indigenous roots, colonial influences, and more recent borrowings, illustrating how different historical and social contexts shape its structure and use. Understanding strata helps linguists analyze language change and diversity.
