Forms

îndeplini (third-person singular present îndeplinește, past participle îndeplinit) 4th conjugation[1] The oldest texts have the verb without the prefix, deplini: „Să-i lumineze pre fiii Românilor și să-i deplinească” “to enlighten the sons of the Romanians and make them perfect” (Petru Maior).[2][3]

Etymology

It is formed from Romanian în- + deplin (“full, complete”).[4][5][1] DA describes it more exactly as a derivative of the adjective, first deplini, to which the prefix was added later.[2] Ciorănescu lists it in the family of plin “full”.[6] The adjective is itself from Romanian de- + plin,[7][1] and its base is from Latin plēnus (“full”).[6] The older verb împlini “to fill, fulfil” is built on the same adjective.[6]

Earliest recorded meaning

Tiktin dates the verb from Petru Maior's history of 1812, where the form is still deplini “to make perfect”.[3][2] The Lexicon de la Buda (1825), MDA2's first record, also has deplini.[5][2] The noun deplinire is older: the Bible of 1688 has „întru toată deplinirea” “completely, utterly”.[2]

Semantic evolution

DA records four senses: to fulfil (a mission, an oath, an order), to take someone's place (Bălcescu: in the Aga's absence he filled his place), to perfect, and to complete (a ration of hay made up with straw).[2] Of these only “to carry out, accomplish” remains common;[5][4] MDA2 marks the others as obsolete.[5][4] Phrases such as a aduce la îndeplinire “to put into effect” belong to the language of administration and law.[2] Tiktin also records the sense “to complete” of a law code being drafted.[3]

Timeline

  • 1812 – deplini “to make perfect” in Petru Maior's history.[3][2]
