The word "光风霁月" is formed by combining two descriptive phrases: "光风", which refers to a bright, clear wind after rain, and "霁月", which refers to a bright, clear moon after rain, with each character contributing directly to this imagery, "光" for brightness, "风" for wind, "霁" for clearing after rain, and "月" for moon, thus creating a compound term that literally depicts a scene of fresh clarity in nature.
