Nexus

Nexus: A connection or link. A causal connection. A connected series.

"Nexus" comes from the Latin "nectere" meaning "to bind." The same Latin root gave rise to "connect" and "annex."

"Nexus" achieved some currency as the title of a book by Henry Miller (1891-1980). Following "Sexus" (1949) and "Plexus" (1953), "Nexus" (1960) completed Miller's "Rosy Crucifixion Trilogy."
