Morphology
supernatant = natant (semi-transparent) = super + natant
The prefix 'super-' is clear, but 'natant' is less commonly known, making the overall meaning less transparent.
Etymology
Supernatant comes from the Latin parts super 'above' and natare 'to swim'. In a lab, the supernatant is the clear liquid that sits on top of the solid after the mixture has settled.
