Resplendent
Etymology
From Latin "resplendent-," the stem of "resplendens," the present participle of "resplendere" ("to shine brightly"): "re-" (here an intensive) plus "splendere" ("to shine, be bright"). That same root gives us "splendid" and "splendor." The word has always meant glowing with brilliance.
adjective · /rih-SPLEN-dunt/
Shining brilliantly; dazzlingly bright or splendid in appearance.
What it names
The word for something so bright and magnificent that it commands attention — a figure in full ceremonial dress, a sky ablaze at sunset.
Example
The general appeared resplendent in his medals and gold braid.
Related idea
Splendid praises something as excellent or grand in general; resplendent narrows that to a literal, dazzling brightness of appearance.
