Etymology: Pentadic is a plain formation: English "pentad" with the adjectival suffix "-ic" attached. The "-ic" ending traces back through Latin "-icus" and Old French "-ique" to a Proto-Indo-European adjectival suffix, and it reached English through Middle English "-ik". The suffix is the part that makes the word an adjective, turning a noun for a group into a description of things belonging to or arranged around that group. The noun it builds on, "pentad", comes from Greek "pentas", meaning a group of five, with the root "pente" meaning five. The Greek root, the same as in "pentagon" and "Pentateuch", is what gives the word its numerical sense. So "pentadic" literally means "of or relating to a pentad," which is why the word can describe any structure organized in fives.
