substratiivisia
Substratiivisia refers to phenomena or features that are retained from a previous linguistic substrate when a new language is adopted or imposed upon a population. This typically occurs during language shift or language contact situations where a dominant language replaces an older, indigenous language. The influence of the substratum language can manifest in various ways within the newly adopted language, often referred to as the superstratum language.
These influences can be observed in phonology, such as the retention of specific sounds or pronunciation patterns
Grammatical structures can also be affected, though this is generally considered a deeper and more pervasive
