The anthroponym Irina became Jerina and it can be seen from three aspects: (1) From the aspect of phonetic adaptation of the anthroponym: the Greek name "Irina" became the Serbian name "Jerina"; (2) from the aspect of derivation of the appellative "jerina" (the ruins of an old town) from the anthroponym "Jerina", and (3) from the aspect of the change in the meaning of the name "Irina" (meaning "peace" in Greek) into the name which bears a negative connotation in Serbia and the name that becomes a protective name: that is, the new-born female children, in the families which have no male children, are named Jerina in order to stop the birth of further female children.
