What does sunburst mean?
Sunburst literally describes a sudden outbreak or spreading of sunlight, particularly the dramatic appearance of rays. In design and decorative contexts, it names a motif in which lines or rays radiate from a central point; objects bearing such a pattern may also be called sunbursts, as in a sunburst clock. Figuratively, the word applies to a sudden display of brilliance, warmth, beauty, or emotion: a person’s smile or an event’s effect might be described as a sunburst. The compound combines the ordinary words sun and burst, making its imagery especially vivid. It suggests light radiating outward with force and abundance, giving the word a positive, energetic character in many contexts. Although sunburst is firmly established in general English, some figurative uses sound more literary or celebratory than plain or technical.

Where does sunburst come from?
Sunburst is an English compound formed in the early 17th century from sun and burst. Sun descends from Old English sunne, while burst comes from Old English berstan, meaning “to break” or “to burst”; German Sonne and Dutch zon, as well as German bersten, are cognates of the respective components. The compound originally conveyed a sudden outbreak of sunlight, a sense that also underlies its figurative use.
