Alabanian "ngujon"

I should like to know if there is any work about Latin loans into
Albanian since it should better to read by myself instead of asking :is
this so?, is that so?, etc.

For instance in this case, there is the Albanian verb "ngujon". I have
no ideea about this one if this is a latin loan or not. If this is a
Latin loan, then the Latin verb wherefrom the Albanian "ngujon" derive,
should be the verb "incuncare" ( my opinonin).
If yes, then how is to explain the /nc/ > /j/ ?
