Etymology
() Calque of complex, by Hermann Weyl|Hermann Weyl]]. Complex comes from the Latin complexus (“braided together”) (from com- (“together”) + plectere (“to weave, braid”)), while symplectic comes from the corresponding Ancient Greek sym-plektos (συμ (sym), variant of σύν (syn) + πλεκτικός (plektikós), from πλέκω (plekō)). In both cases the suffix comes from Proto-Indo-European *plek-. Previously, the “symplectic group” had been called the “line complex group”.
