Morphology

osmolarity = osmolar (semi-transparent) = osmole + ar + ity

Forming a noun from the adjective 'osmolar' with '-ity' is a regular and predictable derivation.

Etymology

Osmolarity comes from the Greek root osmos meaning 'a push' and the ending -arity, like in molarity. Think of osmosis, where water moves because particles 'push' it, so osmolarity measures how many dissolved particles are in a solution and tells us how water will move.
