Usage: Use "splendid" to describe something magnificent or excellent, but avoid using it as a direct synonym for the physical brightness defined in this entry unless emphasizing radiance. It is often preferred over more formal terms like "magnificent" in casual praise of quality or appearance.
The word splendid comes from the Latin splendēre, meaning to shine. It entered English with this original sense of radiating light or brilliance.
