   • c. 1260, Rumi, “2:1080−1081”, in The Masnavi:

     ‏چون کسی کاو از مرض گل داشت دوست، گر چه پندارد که آن خود قوت اوست، قوت اصلی را فرامش کرده است، روی در قوت مرض آورده است.‎‎

     čon kas-i k-u az maraz gel dâšt dust, gar če pendârad ke ân xod qut-e u-st, qut-e asli-râ farâmuš karde ast, ruy dar qut-e maraz âvorde ast.

     As [in the case of] one who from disease has become fond of [eating] clay—though he may suppose that that [clay] is indeed his [natural] food, he has [in reality] forgotten his original food and has betaken himself to the food of disease.

     (Reynold A. Nicholson translation)

• کسی‎ (kasi)
• هیچ‌کس‎ (hič-kas)

From Proto-Indo-European *kuḱis (“(female) pubic hair; vulva”). Cognate with Northern Kurdish quz (“vagina, vulva, cunt, pussy”), Hawrami [script needed] (kʷsî, “vulva”), Lithuanian kūšỹs (“pubic hair, vulva”) and Latvian kūsis (“public hair, vulva”). Possibly a euphemism from the older meaning "belly", preserved in Sanskrit कुक्षि (kukṣí, “belly”). Old Armenian կոյս (koys, “virgin”) may be an Iranian borrowing. Note also Ancient Greek κυσός (kusós, “vagina; anus”).

• (Iranian Persian) IPA^(key): [kʰos]
