Illuminates

Illuminates is the third-person singular present tense form of the verb illuminate. It denotes the act of lighting up or making something clearer. In literal usage, it describes causing light to fall on a subject, enabling visibility, as in streetlights that illuminate the road at night or a window that illuminates a room with daylight. In figurative usage, it means to clarify or explain something, for example a comprehensive analysis that illuminates the relationship between variables.

Etymology and forms: illuminate comes from Latin illuminare, from lumen meaning light. The word entered English through Old French and Middle English, retaining both the sense of physical lighting and the sense of intellectual or perceptual clarity. The noun illumination shares the same roots and is used for the act of lighting or for metaphorical enlightenment.

Usage notes: Illuminates is a transitive verb and requires a direct object. It is common in scientific writing when describing results that reveal mechanisms, as well as in journalism and literature to describe explanations that increase understanding. The term is closely related to illuminate (the base form) and to the noun illumination, which can refer to lighting as a physical phenomenon or to figurative insight. In design contexts, illumination refers to planned lighting to improve visibility and ambience.
