Forms
κλέπτης (kléptēs) m (genitive κλέπτου, feminine κλέπτῐς); first declension[1]
Etymology
It is formed from Ancient Greek κλέπτω (kléptō, “to steal”) + -της (-tēs), an agent noun.[1][2][3] Beekes takes the verb as a Greek renewal of an older present seen in Latin clepō (“I steal”), from a root Proto-Indo-European *klep- (“to steal”) that may be a western development of a verb for “grab”.[2]
The Etymologicum Magnum derived it from καλύπτω (kalúptō, “to cover”), since a thief takes things in secret, but Beekes rejects any link between the verbs for “steal” and “cover”.[4][2]
Earliest recorded meaning
In a simile of the Iliad a mist on the mountains is no friend to the shepherd but better than night to the thief.[3][5][6]
Semantic evolution
Aeschylus calls Prometheus the thief of fire, and Sophocles uses the word more generally for a cheat or knave.[5][7] In Attic it is the plain thief, set beside the robber, as in Plato's Republic, or against him, as in the comic poet Myrtilus; the orators and Plato also use it for those who embezzle public money.[5][7] Aristotle names a logical fallacy “the thief's argument”.[5]
The Septuagint uses it in the laws on theft, and the New Testament says that the day of the Lord comes “like a thief in the night”, calls Judas a thief and calls the false leaders who came before Jesus thieves and robbers.[8][6] It was borrowed as Latin clepta.[9]
Medieval Greek pronounced it κλέφτης (kléftis), with /pt/ becoming /ft/, for a thief, a robber or an abductor.[10][11] In Modern Greek κλέφτης (kléftis) is a thief, and also one of the klephts, the bands that took to the mountains during Ottoman rule and formed the resistance to Turkish abuses.[11]
