错综 (cuò zōng) is an adjective meaning 'intricate,' 'interwoven,' or 'complexly entangled.' Literally, 错 (cuò) means 'to interlace' or 'to be misplaced,' and 综 (zōng) means 'to weave together' or 'to integrate.' Together, they evoke the image of threads crossing and intertwining in a dense, non-linear pattern — like roots beneath a forest floor or vines climbing a trellis. The word emphasizes structural complexity and mutual interdependence rather than mere difficulty.

It's commonly used to describe natural systems (e.g., root networks, river deltas), abstract relationships (e.g., historical causes, social dynamics), or artistic compositions (e.g., embroidery, musical counterpoint). Though occasionally found in formal writing or academic contexts, it rarely appears in casual speech. It often pairs with nouns like 关系 (guānxi, 'relationships'), 结构 (jiégòu, 'structure'), or 现象 (xiànxiàng, 'phenomena') to highlight layered, non-hierarchical complexity.
