NOW WHAT ARE THESE LANGUAGE FAMILIES
Let us understand this term by an example. Let's take the example of Kushaite group. Arabic, Hebrew , Berber ,Amharic, Tigrinya, and Tigre etc are the languages of this group. It means that these languages are the daughters of a common language Kushaite i.e. in the past there was a language Kushaite which changed in form with the passing of time (this is a continious process which occurs with all the languages e.g. you can see your own mother language how much it has changed in last 100 years ) .
As Kushaite was changing with the time, its speakers who were in different geographical area developed it in different forms. For example it developed as Berber in Algeria & Morocco and it developed as Arabic in the central area , as Amharic, Tigrinya and Tigre in Ethiopia and as Hebrew in the south Egypt . Thus the languages Arabic, Berber and Hebrew are related to one another and are sister languages of each other. And as this group has no relation with the other lingual groups of the world its daughter languages also have no relation with the other languages of the world.
Similarly the Latin sub-group has five languages Spanish, Portuguese , French, Italian and Romanian which are in existence today. These five languages are the daughters of the same language Latin and have been evolved out of Latin. Thus these are 12 such language-families in the world . The Aryan and the Dravidian families include all the languages of India. The European family includes the languages of , Australia, the United States and Europe . Inkan languages are spoken throughout South America along with eropean, although the precise number of languages in this classification is not known.The Uralic language family & Altaic language family, include over 60 related languages . The most widely spoken Nippo-Tibetan language is Chinese, with over 1 billion speakers. The South East Asian languages, spoken by 45 million people in South East Asian countries. The Polynesian language family is the main language family of the Pacific, spoken from Malaysia to Easter Island and Hawaii. Languages which do not belong to any of these families include language isolates
