"Linguistic" refers to anything related to language and its structure. It encompasses the study of how languages are formed, how they evolve, and how they are used in communication. Linguists, the experts in this field, analyze various aspects of language, including grammar, vocabulary, and pronunciation, to understand how people convey meaning.
In addition to studying individual languages, linguistic research often explores the connections between different languages and cultures. For example, comparative linguistics examines similarities and differences among languages, while sociolinguistics looks at how language varies in different social contexts. This helps us appreciate the rich diversity of human communication.
