Vajk, Voyk or Vojk (alternatively spelled Vayk in English, Voicu in Romanian) is an Old
Hungarian masculine first name supposedly derived from the
Turkic Bajik (or Bajiq or Bayk)[1] which meaning is "True Man"[2] or "rich, powerful".[3][better source needed]Tatars used the name 'Bayk' till the 18th century.[4]More likely it is of Slavic origin from
Vojko as the Romanian name Voicu. [5]
