Morphology
quaternary = quatern (semi-transparent) = quatern + ary
The root 'quatern' is not a standalone English word but indicates 'fourth', making the transformation semi-transparent.
Etymology
The word quaternary comes from the Latin part quater- meaning 'four' or 'four times', the same root you see in quarter and quartet. So a quaternary stage is the fourth one, the part that comes after the third.
