These adjectives mean having parts so interconnected as to hamper comprehension or perception of the whole. Complex implies a combination of many interwoven parts: The composer transformed a simple folk tune into a complex set of variations. Complicated stresses a relationship of parts that affect each other in elaborate, often obscure ways: The party's complicated platform confused many voters. Intricate refers to a pattern of intertwining parts that is difficult to follow or analyze: "No one could soar into a more intricate labyrinth of refined phraseology" (Anthony Trollope).
Involved implies a close but confusing interconnection between many different parts: The movie's plot was criticized as being too involved. Tangled strongly suggests the random twisting of many parts: "Oh, what a tangled web we weave, / When first we practice to deceive!" (Sir Walter Scott).
