farina (n.)

1707, "dust, powdery substance," from Latin farina "ground wheat, flour, meal," from far (genitive farris) "husked wheat, emmer; grain, flour," from Proto-Italic *fars "flour," from PIE *bhars-, with cognates in Old Irish bairgen "bread, loaf," Welsh bara "bread," Serbo-Croatian brašno "flour, food," Latvian bariba "food," Gothic barizeins "from barley," Old Norse barr "grain," Old English bere "barley;" according to de Vaan perhaps a loan-word from a non-IE language.
