χοῖρος

Traditionally derived from Proto-Hellenic *kʰóřřos, from Proto-Indo-European *ǵʰóryos (“pig”) (whence Proto-Albanian *darja and Albanian derr), from *ǵʰer- (“to be excited, bristly”) +‎ *-yos, whence *ǵʰḗr (“hedgehog”). But in view of limited distribution Beekes suspects a substrate origin.

χοῖρος • (khoîros) m (genitive χοίρου); second declension

1. a pig, especially a young one.
   • 446 BCE – 386 BCE, Aristophanes, The Archarnians 521:

     Κεἴ που σίκυον ἴδοιεν ἢ λαγῴδιον
     ἢ χοιρίδιον ἢ σκόροδον ἢ χόνδρους ἅλας,
     ταῦτ’ ἦν “Μεγαρικὰ” κἀπέπρατ’ αὐθημερόν.

     Keí pou síkuon ídoien ḕ lagṓidion
     ḕ khoirídion ḕ skórodon ḕ khóndrous hálas,
     taût’ ên “Megarikà” kapéprat’ authēmerón.

     And if they see a cucumber or a young hare
     or a piglet or a clove of garlic or a granule of salt,
     They would shout "Megarian!" and take it all away.

2. (generally) swine
3. (slang, vulgar) female genitalia, especially those belonging to a young woman
   • 446 BCE – 386 BCE, Aristophanes, The Archarnians 782–783:

     Νῦν γε χοῖρος φαίνεται.
     ἀτὰρ ἐκτραφείς γε κύσθος ἔσται.

     Nûn ge khoîros phaínetai.
     atàr ektrapheís ge kústhos éstai.

     Now it looks like a pussy.
     But once it's been reared, it'll be a cunt.

4. a fish of the Nile

• For the semantic shift of “pig” to “female genitalia”, compare the same Latin use of porcus.
