The word 感恩节 is formed by directly combining the core concept of "giving thanks" (感恩) with the idea of a "festival" or "holiday" (节). It is a conceptual fusion, creating a new term that names a specific celebration by describing its essential purpose, a holiday dedicated to the expression of gratitude. This formation mirrors the way the English name "Thanksgiving" itself is constructed, conceptually translating the holiday's essence into Chinese cultural and linguistic imagery.
