means To give off or reflect light, to gleam or glow — or figuratively, to perform with conspicuous excellence.

from From Old English 'scinan,' to give light, descending through Proto-Germanic 'skinan' (a cousin of German 'scheinen' and Dutch 'schijnen') and ultimately tracing back to a Proto-Indo-European root '*skai-' meaning to gleam or shimmer — the same ancient glimmer believed to underlie words like 'sheer.' The metaphorical 'shine' — outdoing everyone in the room — and the slang 'take a shine to' are far later flourishes, but the core word is one of English's oldest and brightest.
