The distinction between linguistics and philology is primarily a matter of attitude, purpose, and emphasis.1

Philology is traditionally defined as the historical study of language, often focusing on the analysis of written texts within their cultural and literary contexts. It employs a descriptive framework to examine the historical development of languages.21

In contrast, modern linguistics is the scientific study of language. While linguists may study historical development, they prioritize the analysis of spoken language and its operation at specific points in time. Linguistics is characterized by a broader theoretical scope, often dividing its focus into synchronic (language at a given time) and diachronic (historical development) approaches.1

While philology remains influential in certain academic departments, it has been largely supplanted by linguistics, which treats historical data as part of broader theoretical discussions regarding the nature of language change. Linguistics seeks to construct general theories of language structure, whereas philology remains more closely tied to the painstaking analysis of historical documents.21
