Instead of "primitive language," you might be thinking about:
* Early languages: These are languages that have been reconstructed by linguists based on their relationship to later languages. They may not be fully understood but are considered to be ancestors of modern languages. Examples include Proto-Indo-European, Proto-Sino-Tibetan, and Proto-Niger-Congo.
* Languages with simple structures: Some languages have simpler grammatical structures than others. However, this does not mean they are "primitive." All languages are equally complex in their own way and serve the same functions for their speakers.
* Languages spoken by small, isolated groups: These languages may not be as widely spoken or well-documented as larger languages, but they are just as complex and sophisticated.
It's important to remember that all languages are complex and evolved over time. There is no such thing as a "primitive" language.
Instead of using the term "primitive language," consider using more specific and accurate terms such as:
* Early language
* Language with a simple grammatical structure
* Language with limited documentation
* Language spoken by a small, isolated group
This will avoid perpetuating the misconception that some languages are less sophisticated than others.
