Forms

nebuni (first-person singular present nebunesc, third-person singular present nebunește, past participle nebunit), 4th conjugation[1][2]

Etymology

It is formed from Romanian nebun (“mad”) + -i, the adjective with the verb suffix -i.[2][3][4][1][5] The adjective is itself formed on bun “good, sound” with the negative prefix ne-, and bun goes back to Latin bonus (“good”).[1] DELR and Ciorănescu both list the verb in the family of bun;[4][6] Ciorănescu gives înnebuni as its variant.[4][6] The prefixed verb, formed with în-, is the usual one today, and the dictionaries define the simple verb by it.[7][2][8]

Earliest recorded meaning

DELR dates the verb to 1566, in a print of Coresi, with the senses “to drive out of one's mind” and, reflexive, “to become hostile”.[4] MDA2's first record is Coresi's Carte de învățătură of 1581, where lust drove the wise Solomon to sacrifice to idols: „Curviia amu pre preamîndru Solomon, spre a idolilor jărtvă, nebuni-l”.[3][5] In the same book the scribes, unable to understand, „de pizmă topiia-se şi nebuniia” “were wasting away with envy and raging”.[5]

Semantic evolution

In the old language the verb, often reflexive, meant to grow hostile, to rage, to harden against someone or to rebel: the DLR quotes the New Testament of 1648 and the Bible of 1688.[5][3] The Slavonic–Romanian lexicons of the 17th century, from Mardarie's of 1649 on, use nebunesc for Slavonic verbs of raving and playing the fool.[9] The transitive sense “to drive mad” had a moral side as well, to corrupt or to befuddle someone, as in the folk line „Dragostea te nebunește” “love drives you mad”.[5][3]

Today the simple verb is popular, and the standard language says înnebuni.[2][10] It survives in the familiar Nu mă nebuni!, said in surprise or disbelief, and in reflexive a se nebuni după “to be crazy about”.[2][3]
