Etymology
It is inherited from Middle English chese,[5][2] inherited from Old English ċēse, Anglian, and cȳse, West Saxon,[1][5][6] from Proto-West Germanic *kasjus,[1][6] also the source of Old Saxon kāsi, German Käse and Dutch kaas,[1][5] an early borrowing from Latin cāseus (“cheese”),[1][5][6] which also gave Italian cacio, Spanish queso and Welsh caws.[1] The Latin word is of uncertain origin:[5][1] Watkins suggests a root *kwat- “to ferment, become sour”, but de Vaan finds no etymology without weak assumptions and suggests a loanword.[1] The Scandinavian words, Danish and Swedish ost, are unrelated.[1]
Earliest recorded meaning
Old English cāse is from 800, in an early glossary, and cyse from before 1000, in Ælfric's Colloquy;[5] the OED's first quotation is from before 1000.[3]
Semantic evolution
The earliest references are to pressed curds of milk; pressed or moulded cheeses with rinds are from the 14th century,[1] 1362 in the OED.[3] The surname Chesemangere is from 1186.[5] Chalk and cheese is from about 1425.[3] Other cheese-like substances are called cheese from the 1530s.[1] As a photographer's word to make people smile, and school slang for a smile, it is from 1930.[1][3] Hard cheese, bad luck, is from 1876.[3] Big cheese, an important person, is from 1914 in American English and probably belongs with this word,[1] and cut a big cheese, to look important, is from 1915.[1]

cheese2 the right thing
- Confidence
- Probable
- Formation
- Borrowing
- First attested
- 1818
- Borrowed from
- Persian چیز
- Ultimate origin
- Persian (چیز)
Etymology
It is probably from Urdu chīz “thing”, borrowed from Persian چیز (čiz, “thing”),[1][2][7] from Old Persian *ciš-ciy “something”,[1] picked up by the British in India.[1] Wiktionary notes that the word does not appear first in Anglo-Indian sources, which casts doubt on this.[7]
Earliest recorded meaning
1818, as slang for the right or correct thing, anything first-rate.[3][1][2]
Semantic evolution
It was used especially in the phrase the real chiz, a big thing.[1] Wealth and fame, and an important person, are from before 1910 in the OED,[3] but Etymonline thinks the American big cheese more likely belongs to the food word.[1]
