lucru n (plural lucruri)[1]

Etymology

It is inherited from Latin lucrum (“material gain, profit”) according to Pușcariu and the REW, a view Ciorănescu accepts as probable.[2][3][4][5] The word exists in all four branches: Aromanian lucru, Megleno-Romanian lucru and Istro-Romanian lucru.[2] The Latin noun goes back to Proto-Indo-European *leh₂w- (“profit, gain”).[1][5]

It may instead have been formed in Romanian from the verb lucra, itself from Latin lucrō (“to gain”);[1][6] Wiktionary gives both explanations, and the Romanian Wiktionary takes the noun as a back-formation from the verb.[1][6][2] Ciorănescu calls the shift from “to gain” to “to work” normal, comparing French travailler, which can also mean “to bring in money”.[2] The REW compares the range of meanings “business, matter, thing” with Bulgarian, Slavonic and Modern Greek words for “work” that have the same senses.[4]

Earliest recorded meaning

The plural lucrurile and the form lucrul occur in the Psaltirea Hurmuzaki of the early 16th century, in the sense “works, deeds”.[7][8] The old sense “gain, profit” appears in Coresi's Evanghelie cu învățătură of 1581, MDA2's first record.[3][9] Tiktin's first record is the Psaltirea Scheiană.[10]

Semantic evolution

The Latin sense “gain, profit” survived into the 17th century, with the phrase fără (de) lucru “without profit, in vain” and also “wrongfully”: a document of 1591 says that someone had entered an estate fără lucru, without right.[3][9][10] From “gain” and “business” the word came to mean work and activity, and then any thing or object, which is its main sense today.[2][11]

The 17th-century Slavonic–Romanian lexicons use it to translate Slavonic words for “deed” and “work” as well as for “thing”.[12] In legal language it names movable and immovable property, and in philosophy Kant's “thing in itself” is lucru în sine.[11][3]
