Sparkling or glittering; covered with sparkles or shining brightly with a shimmering effect.
From Old English 'a-' (prefix indicating state or condition) + 'sparkle' (to emit sparks). The prefix 'a-' here intensifies the meaning, similar to 'ablaze' or 'alight.'
Poets love 'asparkle'—it appears in literature to describe dewdrops on morning grass or stars on a clear night. It's one of the few 'a-' prefix words that survived into modern English, probably because it sounds so musical and evocative.
