Morphology

commensurability = commensurable (semi-transparent) = com + mensur + able + ity

The transition from 'commensurable' to 'commensurability' is transparent, but the root 'mensur' is less recognizable to learners.

Etymology

Commensurability comes from Latin parts com- 'together' and mensura 'measure', so it literally means 'measuring together'. In mathematics this means two lengths have a common measure and their ratio can be written as a simple fraction.
