English[edit]
Etymology[edit]
From Latin septem (“seven”) + Ancient Greek γωνία (gōnía, “angle”), equivalent to septa- + -gon.
Pronunciation[edit]
Noun[edit]
septagon (plural septagons)
- (proscribed) A polygon with seven sides and seven angles.
Usage notes[edit]
Because septagon is formed by combining Latin septem (“seven”), with Ancient Greek γωνία (gōnía, “angle”), it may be considered less correct than heptagon, which has a fully Greek etymology.
