cheese (n.)
O.E. cyse "cheese," from W.Gmc. *kasjus (cf. O.S. kasi, O.H.G. chasi,
Ger. Käse, M.Du. case, Du. kaas), from L. caseus "cheese" (cf. It.
cacio, Sp. queso, Ir. caise, Welsh caws), perhaps from a PIE base
*kwat- "to ferment, become sour" (cf. Prakrit chasi "buttermilk;"
O.C.S. kvasu "leaven," kyselu "sour," kyseti "to turn sour;" Skt.
kvathati "boils, seethes," Goth. hwaþjan "foam"). Also cf. fromage.
Earliest references would be to compressed curds of milk used as food;
pressed or molded cheeses with rinds are 14c.
As a photographer's word to make subjects hold a smile, it is attested
from 1930, but in a reminiscence of schoolboy days, which suggests an
earlier use. To make cheeses was a schoolgirls' amusement (1835) of
wheeling rapidly so one's petticoats blew out in a circle then
dropping down so they came to rest inflated and resembling a wheel of
cheese; hence, used figuratively for "a deep curtsey." Cheese as "the
proper thing," and perhaps in expressions such as big cheese, is from
Urdu chiz "a thing," from Persian chiz, from O.Pers. *ciš-ciy
"something," from PIE pronomial stem *kwo- (see who). Picked up by
British in India by 1818 and used in the sense of "a big
thing" (especially in the phrase the real chiz).
