Ižakovci was attested in written sources in 1322 as Isakouc and Isacoush (and as Isakolch in 1381 and Isakowlch in 1428). The name of the settlement is derived from personal name Izak 'Isaac' and is a demonym meaning 'inhabitants of Isaac's village'. The phonemic change -z- > -ž- indicates that the Slovenian name developed through an intermediate German form.[6]
