Diaphanousness refers to the quality of being transparent or sheer, allowing light to pass through easily. Some synonyms for diaphanousness include translucency, gauziness, sheerness, and delicacy. Translucency suggests the ability to allow some light to pass through, but with some degree of opacity. Gauziness implies a thin and sheer quality, often associated with fabrics or materials like gauze or chiffon. Sheerness refers to a lack of opacity or thickness, allowing light to pass through unobstructed. Delicacy implies a lightness and fragility, often used to describe delicate fabrics like lace or organza. All of these words suggest a subtle and ethereal quality that is characteristic of diaphanousness.
