Forms
cui n (plural cuie)[1] Banat has the variant cuń.[2][3]
Etymology
It is inherited from Latin cuneus (“wedge”), a word continued throughout Romance.[2][4][5][6][3][1] The REW, Pușcariu, and Candrea and Densusianu give the same source.[4][7][8] The origin of the Latin word is unclear: a link with culex (“gnat”) meets a problem of vowel length, and De Vaan finds a loan from Ancient Greek γώνιος (gṓnios, “angular”) through Etruscan unconvincing.[9][1]
The word survives in Istria: Istro-Romanian cuñu.[2][4][10] Wiktionary takes Aromanian cunj from the same Latin word, perhaps through another language.[1] Albanian kunj is a loan from the same Latin word.[11][4] The Romance cognates include Italian cogno, French coin, Occitan cunh, Catalan cuny, Spanish cuño and Portuguese cunho.[4][7]
Earliest recorded meaning
The first record is the place name Kunj of 1341.[2][3] As a common noun it is first attested in 1508.[2]
Semantic evolution
The Latin wedge survives in Maramureș, where cui is a wedge for splitting logs.[5][2] Elsewhere the word came to mean the nail of wood or metal driven into wood or a wall, also used as a peg to hang things on.[6][2] In Teleorman it also names a wooden bolt and a sharp stabbing pain.[2]
Regional senses include a small glass of brandy in Maramureș, which Ștef links to the saying cui pe cui se scoate, and a children's colic in Muntenia.[12][13][14] In slang it names a joint or a hypodermic needle.[15] Derivatives are dated from the 17th century: cuńișor “small nail; clove” about 1650, and cuier “nail maker” in Corbea's dictionary (1691–1697).[2]
