A feminine noun meaning tail, used exclusively in Revelation to describe the terrifying appendages of apocalyptic creatures. The locusts of the fifth trumpet have tails like scorpions with stingers that torment for five months (Rev 9:10). The cavalry horses of the sixth trumpet have tails like serpents, with heads that inflict harm (Rev 9:19). The great red dragon's tail sweeps a third of the stars from heaven (Rev 12:4). The Spanish 'cola,' French 'queues,' and German 'Schwänze' all denote animal tails straightforwardly, but in Revelation the word is loaded with symbolic menace.
