کس

From Middle Persian AYŠ (kas, “person, somebody”).

کس • (kas) (plural کسان (kasân))

1. (archaic) person
2. one, person, somebody (in relative clauses)
   • 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 farâmoš 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 (“pubic hair, vulva”). Possibly a euphemism from the older meaning "belly", preserved in Sanskrit कुक्षि (kukṣí, “belly”), in Sogdian qwšy (“side (e.g. of the body)”) and in Persian کشتی (kuštī, “girdle”). Old Armenian կոյս (koys, “virgin”) may be an Iranian borrowing. Note also Ancient Greek κυσός (kusós, “vagina; anus”).
