Etymology
Sense 1 (“subatomic particle”) was coined by the American physicist Murray Gell-Mann (1929–2019) in 1963, apparently an arbitrary word. Subsequently, in a letter dated 27 June 1978 to the editor of the Oxford English Dictionary Supplement, Gell-Mann associated the word with the sentence “Three quarks for Muster Mark!” from James Joyce’s Finnegans Wake (1939) and indicated that he pronounced the word /kwɔɹk/, reasoning that the sentence referred to a call in a pub for “three quarts”. However, the context in the book indicates that quark is probably a variant of quawk (“harsh call of a bird”) and was intended by Joyce to be pronounced /kwɑːk/, the modern pronunciation.
