Forms

înnebuni (third-person singular present înnebunește, past participle înnebunit) 4th conjugation[1]

Etymology

It is formed from Romanian în- + nebun, “insane, mad”, as DEX, MDA2 and Wiktionary give it.[2][3][1] The DA is more exact: the verb was first nebuni, derived from the adjective, and took the prefix în- only later.[4] Ciorănescu also lists the unprefixed verb as the main form, with the prefixed one as its variant, and DELR derives the verb from the adjective.[5][6] The adjective is itself formed from Romanian ne- + bun, “not good”, and bun is from Latin bonus.[7][6]

Earliest recorded meaning

Tiktin dates the first record to Coresi's Praxiu of 1563.[8] MDA2 and the DA cite Coresi's Carte de învățătură of 1581, where lust drove Solomon mad, so that he sacrificed to idols, with the form without prefix.[3][4] DELR gives 1794 for the prefixed form.[6]

Semantic evolution

The old texts use the verb both transitively, “to drive mad”, and as a reflexive a se nebuni “to go mad”: in the Mărgăritare wicked women bewitch their lovers and „pre unii i-au nebunit” “drove some of them mad”.[4][8] The DA marks the reflexive as old in its time; the intransitive a înnebuni now has the sense “to go mad”.[4]

From “to go mad” came weaker senses: to lose one's composure, and transitively to exasperate or pester someone.[2][9] The colloquial Nu mă înnebuni! “don't drive me mad!” expresses surprise or disbelief at what one hears, and is found in Alecsandri and Caragiale.[4][2] With după, the verb means to be crazy about someone or something, a use Tiktin quotes from Alecsandri, whose Hagi Hristodul „se nebunește după răcituri cu usturoi” “is mad about jellied meat with garlic”.[8][3]
