The Word of the Day for November 12 is:

ennead \EH-nee-ad\ noun
: a group of nine


To the ancients, nine was a very special number, one often associated with gods and divinity. Legends and literature have long characterized groups of nine as having a special, in some cases magical, significance. Ancient Egyptians organized their gods into groups of nine; even today, their principal group of gods (headed by sun god Re-Atum) is called the "Great Ennead of Heliopolis." The "Ennead" English speakers use in that name traces to "ennea," the Greek word for "nine." "Ennead" is also used generally to refer to other groups of ancient gods. Furthermore, it is the name given to six sets of nine treatises by Greek philosopher Plotinus that were collected and organized by his 3rd-century disciple, Porphyry.
