symplectic

EnglishEdit

EtymologyEdit

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 ‎(sum), variant of σύν ‎(sún) + πλεκτικός ‎(plektikós), from πλέκω ‎(plékō)). In both cases the suffix comes from Proto-Indo-European *plek-.

Previously, the “symplectic group” had been called the “line complex group”.
