The name 'Rusonih' is a Slavic compound personal name that originates from the name of the village Rusonih, located in Southern Bukovina. In a document from 1446, it is mentioned: "we have given to our monastery... the villages named Repchichani and Rusonih" - from the city of Suceava. This name consists of two components: 'rus-', which means 'light-haired', and '-nih', which translates as 'care' or 'concern'.
