Pronunciation

Forms

trei[1] Variants are tri and trii (old and regional), old tre and regional trâi.[2] Neculce writes trii: „pănă nu s-au plini trii ani” “until three years had passed”.[3] As a noun it has the plural treiuri, and popular speech has a feminine trele after toate or câte: toate trele “all three”.[2][4]

Etymology

It is inherited from Latin trēs (“three”).[5][2][3][6][7][1] The Latin numeral goes back to Proto-Indo-European *tréyes.[1][8]

The word survives in all four branches: Aromanian trei, Megleno-Romanian trei and Istro-Romanian trei.[5][9][10] Its Romance cognates include Dalmatian tra, Italian tre, French trois and Spanish tres.[5][6]

Earliest recorded meaning

MDA2's and Tiktin's first record is the Codicele Voronețean (c. 1563–1583).[2][11] There it has its plain sense, as in în trei dzile “in three days”.[3]

Semantic evolution

As a noun trei names the figure 3 and a school mark of three;[12] Scriban and Tiktin record the plural treiuri for such marks.[12][11][4] It enters plant names such as trei-frați-pătați “wild pansy” and many phrases: de trei parale “worthless”, a fi cu trei roate la car “to have a screw loose”.[4][2] Tiktin quotes the saying unde sunt doi, cu el trei “wherever two are, he makes the third”, said of someone who is everywhere.[11] Romanian formed treilea “third”, treime “third part; the Trinity” and treizeci “thirty” from it.[5]

  • 1563–1583 – trei in the Codicele Voronețean, the first record.[2][11]
