Morphology

observable = observable (transparent) = observe + able

This noun is a straightforward nominalization of the adjective 'observable' and directly refers to something that can be observed or measured.

Etymology

Observable comes from the verb observe, which means 'to watch'. In science an observable is a quantity you can measure or record in an experiment, so it is a property you can actually 'see' in the results.
