Forms
οὐρᾱ́ (ourā́) f (genitive οὐρᾶς); first declension[1] Ionic οὐρή (ourḗ).[2][3]
Etymology
It is probably inherited from Proto-Indo-European *h₁ers- (“tail”), through a Greek form *ὀρσά: οὐρά stands beside ὄρρος (órrhos) “rump” as κουρά (kourá) stands beside κόρρη.[4][5][1] The closest cognate is Old Irish err (“tail”).[4][5] Reconstructions with *-σι̯- or *-σϝ- are unnecessary.[5][4] Wiktionary also gives the alternative reconstruction *h₃érsos (“backside”).[1]
Beekes notes that the derivative οὐραχός (ourakhós) has a suffix that is probably Pre-Greek, and that the stranger οὐρίαχος (ouríakhos) “butt-end of a spear” might even point to a Pre-Greek origin of the word for “tail” itself, unless the two are unrelated.[4][1]
Earliest recorded meaning
Homer uses it for the tail of a lion lashing its flanks, of a dog wagging its tail, and of the wolves and lions round Circe's house that fawn with their long tails.[2][3]
Semantic evolution
Hesiod, Herodotus and Aristotle use it for the tails of other animals, though not of birds.[2] From Xenophon on it is also the rear or rearguard of an army: κατ’ οὐράν “in the rear”, and Polybius speaks of attacking in the rear; in the tactical writers Aelian and Arrian it is the left wing of a phalanx.[2][3][5] Sophocles used it for the penis, as Hesychius also records from Eupolis.[2][6]
In the Septuagint “head and tail” stand for the high and the low in society, and in Revelation the locusts have tails like scorpions.[7][8] Medieval Greek had the forms νουρά, ορά and ούρα, for the tail of animals, birds, fish, insects and snakes and the back of anything.[9] A separate medieval ουρά, a form of address meaning “lord”, is probably a loan translation of Turkish tuğ, the horse-tail standard of Ottoman officials.[9] It continues as Modern Greek ουρά (ourá), with phrases such as putting one's tail between one's legs.[10]
σκίουρος (skíouros), the source of English squirrel, is often explained as “shadow-tail”, from σκιά and οὐρά, but Beekes considers this a folk etymology.[2][4][11]
