English[edit]

Etymology[edit]

Calque of complex, by 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”.
