-plex

a combining form meaning “having parts or units” of the number specified by the initial element, occurring orig. in loanwords from Latin (duplex); recent English coinages ending in -plex are probably in part new formations with this suffix and in part based on the noun complex: eightplex; Cineplex; Metroplex.
[< Latin -plex, s. -plic-, akin to plicāre to fold, bend, plectere to plait, braid; see -fold]
