Comparative Linguistics is the study of the similarities and differences between languages. It aims to understand how languages evolve over time and how they are related to one another. By comparing vocabulary, grammar, and phonetics, linguists can trace the historical connections between languages, such as those in the Indo-European family. This field also helps in reconstructing ancient languages that are no longer spoken. By analyzing patterns and changes in related languages, researchers can infer characteristics of these lost languages. Comparative Linguistics plays a crucial role in understanding human communication and the development of language as a whole.
