絮叨
xù dao · HSK 7
to talk endlessly without getting to the point
🗣️🧶 絮 = cotton fluff + 叨 = chatter; words padded out like endless cotton stuffing
絮 is the cotton wadding stuffed into quilts; 叨 is to jabber. Put them together and the talk is all soft padding and no point, going on and on. The sound xu-dao even drags like a yawn that keeps unspooling.
