The word "厌恶" is formed through the semantic combination of two characters: "厌" and "恶". "厌" originates from ancient pictographs representing pressure or suppression, later evolving to convey feelings of weariness or disgust, while "恶" is derived from components symbolizing badness and heart, reflecting moral or emotional repulsiveness. Together, they create a compound where both elements reinforce the concept of intense dislike, with "厌" emphasizing the visceral reaction of being repelled and "恶" highlighting the perceived objectionable quality, thus encapsulating the meaning of detestation or aversion.
