Word Origin & History
cheese
O.E. cyse, from W.Gmc. *kasjus, from L. caseus "cheese," from PIE base *kwat- "to ferment, become sour." Earliest refs. would be to compressed curds of milk used as food; pressed or molded cheeses with rinds are 14c. Fr. fromage is from M.L. formaticum, from L. forma "shape, form, mold." 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. Cheeseburger first attested 1938. Cheesecake (c.1440) is first recorded 1934 in slang sense of "photograph of sexy young women." 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."
