What does plex mean?
A plex is a network or intertwined arrangement of related elements. The word is especially associated with anatomy, where it can refer to a group of nerves, blood vessels, or lymph vessels that form a connected system. More generally, it can describe any intricate web of relationships, though such uses are uncommon and may sound formal or literary. Its close relative plexus is much more widespread, especially in scientific and medical contexts. A plex should therefore be understood as a concise, relatively rare synonym for plexus rather than as a distinct everyday concept. The word is useful chiefly when a writer wants to evoke the image of many elements woven together into a functioning whole. In nontechnical prose, network, web, or nexus will usually be clearer and more familiar.

Where does plex come from?
The word comes from Latin plexus, meaning “woven” or “a network,” a participial form of plectere, “to plait” or “weave.” English adopted both plexus and the shortened form plex. Related English words include complex, perplex, and plexiform, all of which preserve the sense of weaving or entanglement.
