protolengua 25
The protolanguage is the abstract reconstruction of the language origin of a language group, either a branch or a family. It is obtained from a comparison of the group applying the methods of historical linguistics. It is important to understand that it is an attempt of construction or reconstruction of a previous language and generally unknown for the most part, and that generally, there are no inscriptions or written references. It is a modern construction on a language above or much older and which seeks to unravel the enigma along the reverse route of the evolution of languages; Road not always known. In fact, as in the case of Indo-European and even more so in the case of the proto-Indo-European, perhaps never found existed.
