Linguistic Reconstruction is a method used by linguists to infer the features of a lost or unknown language by analyzing similarities among related languages. By comparing vocabulary, grammar, and phonetics, researchers can identify patterns and make educated guesses about the original language, often referred to as a proto-language. This process relies on the principle that languages evolve over time, leading to changes in sound and meaning. For example, the study of Indo-European languages has allowed linguists to reconstruct aspects of the Proto-Indo-European language, providing insights into the culture and history of ancient peoples.
