Language Theory is a field of study that explores how languages are structured, used, and understood. It examines the rules and systems that govern language, including syntax, semantics, and phonetics. Researchers in this area aim to understand how language functions in communication and how it influences thought and culture. One important aspect of Language Theory is the distinction between descriptive grammar and prescriptive grammar. Descriptive grammar focuses on how language is actually used by speakers, while prescriptive grammar sets rules for how language should be used. This theory also intersects with fields like linguistics, cognitive science, and sociolinguistics.
