dubiu n (plural dubii)[1]

Etymology

It is borrowed from Latin dubium (“doubt”), a 19th-century learned loan.[2][3][4][1] DELR and Tiktin name Italian dubbio beside the Latin word.[3][5]

The Latin noun is the neuter of the adjective dubius (“hesitant, in doubt”), used as a noun.[3][1] The adjective is built on the stem du- (“two”), probably with an element from the root Proto-Indo-European *bʰuH- (“to be, become”), as in probus and superbus: the idea is “of two forms, double”.[3][6] The same image of “two” lies behind the native Romanian îndoi and îndoielnic.[3]

Earliest recorded meaning

Tiktin's first record is from Gheorghe Șincai's Hronicul, written about 1812, with the sense “doubt”.[5][7] DELR dates the noun from 1861, in Heliade-Rădulescu, who asks who could put the honour of a certain musiu Rapace „în dubiu”, “in doubt”.[3][7]

Semantic evolution

The word has kept the Latin sense “doubt, uncertainty”, and with it the lack of trust in someone or something.[4][7] Its usual phrases are a pune în dubiu “to call into question” and a fi or a sta în dubiu “to be in doubt”.[7][8] Șăineanu's dictionary of 1929 adds a sense “scepticism”.[9]

The Latin family came in at the same time: DELR dates dubios from 1815 (Budai-Deleanu), dubitativ from 1833 and dubita from 1868.[3]

Usage notes

An adjective dubiu, dubie “doubtful”, taken from Latin dubius, was used rarely in the 19th century: Șincai writes that a battle „a fost dubie”, “was undecided”.[7][11] Pontbriant (1862) gives the noun a plural in -uri; the standard plural is dubii.[10][4]
