The word 有意思 is formed through a conceptually intuitive process where the concrete notion of “having” (有) “meaning or thought” (意思) evolves into an abstract, experiential quality. It operates on the metaphor that if something contains or possesses substance for the mind (meaning), it naturally engages one's interest and attention, thereby creating the subjective feeling of being “interesting” or “enjoyable.” The compound thus feels less like a strict grammatical construction and more like a natural semantic fusion, where the literal components seamlessly extend into a common emotional and evaluative impression.
