Language language families moved to specific regions due to

Language families are defined as the languages, which are attributed to each other by similar ancestry before history documentation. These groups share a same origin of their past and have fewer variances in grammar and speech. Comrie, 2009). The major language families include the language isolate. Here, the family has no relatives who are yet known and are hence termed as language isolates as they consist of one language. Researchers have argued that the isolates have or used to have relatives in history but great digging is required to uncover them through linguistic comparison. Examples of such a language family are the Indo-European because it has not shown any relation to any other language even after several types of research (Gray and Atkinson 2003, p. 440)Another significant language family in the world is the proto-language. It is also termed as the mother language as it is based from which all other languages are formed from. Proto- Afro-Asiatic language, proto-Bantu language, and proto-Semitic language have been reconstructed in Africa. Proto- north-west Caucasian language, proto- Kartvelian language and proto- Semitic language have also been reconstructed in the near east. Additionally, proto-Tupian, proto-Mayan and proto-Eskimo languages have been restored in America. The language families are geographically situated in their current areas due to factors such as the physical climate. Most language families moved to specific regions due to the environment and soils to settle and made a living for example through farming. Economic concerns also drew the families to new places where they established their current settlements. For instance in America, the language families expanded to the west where they claimed lands for farming practices.Some of the most influential barriers to language diffusion include physical characteristics such as large oceans hinder the passage of new ideas to other areas. Human aspects such as fear of language change serve as a barrier to language diffusion.
