Bohufal is a hypercorrect form of the ancient Slavic name
Bohukhval. In this name, the sound combination /khv/ was replaced by the unusual foreign phoneme /f/ due to false substitution. Examples of this name can be found in documents:- 1547: Bohufal Hrihorievych, Bohufal Labunskyi;- 1565:
Ivan Bohufal, Pasha Bohufal – defendants of the Kyiv zemsky court.
