Philology is the study of language in written historical sources. It involves analyzing texts to understand their meaning, structure, and evolution over time. Philologists often focus on ancient languages and literature, examining how languages develop and influence one another. This discipline combines elements of linguistics, literary criticism, and history. Philologists may work with various languages, such as Latin, Greek, or Sanskrit, to uncover insights about cultures and societies. Their research helps preserve languages and contributes to our understanding of human communication and expression throughout history.
