"Complect" is a rare word that refers to a complex interweaving of different parts or aspects. It is considered an archaic term and has fallen out of use in modern English. As such, it may be difficult to find antonyms for "complect" that are widely recognized or in common use.
However, one possible antonym for "complect" could be "simplify." This would indicate a reduction or streamlining of various elements or components, rather than their intricate combination. Other possibilities might include "unravel," "disentangle," or "deconstruct," all of which imply a separation or breaking apart of something that was previously tied or bound together.
