Philology, (derived from the Greek, from the terms meaning "loved, beloved, dear, friend" and logos "word, articulation, reason") is a branch of the human sciences dealing with language and literature, specifically a literary canon, combining aspects of grammar, rhetoric, historical linguistics (etymology and language change), interpretation of authors, textual criticism and the critical traditions associated with a given language.

Philology considers both form and meaning in linguistic expression, combining linguistics and literary studies.
