From penta- + -gamy.
Why this word is great
PENTAGAMY — [Noun] The state or condition of having five spouses simultaneously. From penta- ("five") + -gamy ("marriage"), from Ancient Greek γάμος (gámos, "marriage"). Unlike "polygamy" (which sprawls across an indefinite plurality) or "bigamy" (which lingers in the binary), pentagamy is a ledger of exacting symmetry. It is the weight of five rings on a single hand, the logistical ballet of five anniversaries, the careful geometry of a bed built for six—a testament to the human capacity to stretch devotion thin as parchment, until it threatens to tear.
noun
