Forms

Etymology

MDA2, the DLR, DEX and the neologism dictionaries give two sources: it is borrowed from Latin obligātōrius (“binding”) it is borrowed from French obligatoire as well.[2][3][4][5] Tiktin names only the Latin.[6] Wiktionary adds that it can be analysed as obliga with the suffix -toriu.[1]

The Latin adjective, “imposing a legal obligation”, is formed on obligō (“to bind”) with -tōrius; it is a post-classical word of the law books.[7][8] The French word is from the same Late Latin source.[1]

Earliest recorded meaning

Tiktin dates the first record to 1742, and also notes an obsolete feminine noun obligatorie.[6] MDA2 and the DLR start with a document of 1866 in the Uricariul, on the binding character of conventions, in the form obligator.[3][2]

Semantic evolution

In the 19th century the word belonged to law: Negulici in 1848 defines it as having the power to oblige by law, and the Latinist Barițiu writes of the binding force (putere obligatoare) of a law voted in the diet.[9][3] Pontbriant in 1862 still marks it as a neologism.[10] The variant obligator lived beside it;[11] CADE in 1931 gives both forms, with compulsory military service as its example.[11][4] The modern senses are “compulsory, to be followed exactly” and, rarely, “indispensable”.[4][2]

Timeline

  • 1742 – first record cited by Tiktin.[6]
  • 1848 – in Negulici's dictionary of neologisms.[9]
  • 1866 – obligator in a document of the Uricariul.[3][2]
  • 1870 – Costinescu's dictionary glosses it with French obligatoire.[12]

Meanings

Adjective

  1. compulsory, mandatory: that must be followed exactly or must be done; imposed: serviciu militar obligatoriu “compulsory military service”.[4][13]
  2. (rare) That cannot be missing; indispensabil.[4][2]

Usage notes

The variant obligator (feminine obligatoare) is still recorded;[14] MDA2 lists regional obligătoriu and obligător too.[4][2]
