This study focuses on core Ancient Greek loanwords in the field of English philosophy (taking "philosophy"

"metaphysics"

and "ethics" as examples). From an interdisciplinary perspective integrating linguistics and cultural studies

it compares and analyzes the original meanings of these loanwords in Ancient Greek and their evolved forms in modern English

exploring the paths

driving forces

and underlying cultural logic of their semantic changes. The research finds that such loanwords generally follow an evolutionary pattern of "from context-specific concreteness to abstract systematicity": "philosophy" has transformed from a dynamic activity of "the love of wisdom" into a modern "systematic discipline studying fundamental questions"; "metaphysics" has solidified from a textual ordering concept of "works after Physics" into a "philosophical branch studying the essence of existence"; and "ethics" has expanded from "the cultivation of citizens' character in city-states" to a "disciplinary field exploring moral norms and value judgments". The deep-seated driver behind the semantic evolution lies in the "modern transformation" of Ancient Greek philosophy in Western culture—its theological interpretation in the Middle Ages

rational reconstruction during the Enlightenment

and pluralistic interpretation in modern times have collectively promoted the adaptation of these loanwords to the ideological needs and disciplinary systems of different eras. This study not only reveals the value of loanwords as a carrier of "language-culture" interaction but also provides a theoretical reference for research on the connection between classical civilization and modern language from the perspective of English majors.
