means A subtle, often deniable insult or expression of contempt — but also, plainly, the darkness cast when something blocks the light.

from From Old English 'sceadu,' meaning shadow or darkness, a cousin of words across the Germanic family for shade and shelter. The slang sense — 'throwing shade,' delivering a sly disrespect — rose through African American and Latino LGBTQ ballroom culture, documented in the 1990s and going mainstream after. The logic is poetic: shade is something you cast on someone, dimming their light without ever raising your voice.
