Pronunciation

Forms

nebun m or n (feminine singular nebună, masculine plural nebuni, feminine/neuter plural nebune)[1] MDA2 records the regional forms nabun and năbun.[2] The DLR adds neabun and năbun from the linguistic atlas.[3]

Etymology

It is from Romanian ne- + bun (“good”): the negative prefix added to the adjective, so that its first meaning was “not good, bad”.[2][4][3][1][5] bun is from Latin bonus (“good”).[6][1] Șăineanu explained the shift to “mad” by an old view of the insane as obstinate and wicked people.[7]

The chess sense “bishop” is a semantic loan from French fou, which goes back through Spanish alfil to Arabic الفيل (al-fīl, “the elephant, chess bishop”).[1]

Earliest recorded meaning

The first record is in the Psaltirea Hurmuzaki (c. 1500–1520), where a sinner stands on every way that is nebun, “not good, evil”.[2][3] A text of about 1550 speaks of a cloud of fire coming from “wicked men” (oamenilor nebuni).[3] Tiktin's earliest citation is the Codicele Voronețean, at 1 Peter 2:15.[8]

Semantic evolution

In the old language the word kept the literal sense “not good”, which gave the senses “sinful”, “stubborn”, “lazy”, “wicked” and “worthless”, now archaic or popular.[2][3] The sense “foolish, senseless” is also old, and “insane, mad” became the main sense of the modern language.[2][4][8] From it come casă de nebuni “madhouse”, nebun după “crazy about, madly in love with”, and the intensive sense “immense, wild”: un succes nebun, o ură nebună.[8][5][4]

Regionally, poisonous mushrooms are bureți nebuni and an unnamed kind of large apple mere nebune.[8][2][5] As a noun the word also named a court jester.[4][5] In the chess sense it occurs in Alecsandri's poems.[3]
