Linguists are experts who study languages and their structures. They analyze how languages are formed, how they evolve over time, and how they are used in communication. This field includes various sub-disciplines, such as phonetics, which focuses on sounds, and syntax, which examines sentence structure. In addition to studying language structure, linguists often explore the social aspects of language, including sociolinguistics, which looks at how language varies among different groups. They may also work in applied fields, such as language education or translation, helping people learn new languages or communicate across cultures.
