Virac () is a commune in the Tarn department and Occitanie region of southern France.
The old forms are Viragio, towards 1100, Virag, in 1135, and according to Negre, Virac comes from the Latin name of man Virius with the suffix -acu-, Latinization of the Welsh suffix -ÃÂco(n). Virac was therefore perhaps an old great ancient property that had for teacher Virius. The choice of Black supposes the absorption of the second -i- by -r-. Always with -acum, Dauzat and Rostaing consider that the name of person is a Welsh name of man, *Viros, choice that is not far from that of Xavier Delamarre, Vërios (from the adjective vëro-, "fair, true", different from viro-, "man"); for Delamarre, the name of origin would be UëriÃÂcon (this also supposes the later absorption of the second -i-, a phenomenon that, always for Delamarre, does not seem automatic: the same etime leads according to him to Viriat and Virieu, Arpitan places).
