The word "星星" is formed through the process of reduplication, where the single character 星 (xīng), meaning "star", is duplicated. This repetition creates a new term that evokes a semantic shift from a single, specific celestial body to a more general, plural, or diminutive concept, like the collective, twinkling expanse of stars in the night sky or the affectionate sense of "little star". The formation relies entirely on visual and conceptual repetition to soften and pluralize the original idea, creating a sense of multiplicity and diffuse light directly through its doubled form.
