A model feature that lets you find only one set of values from data

relates to measuring a system's internal state from outputs rather than parameter uniqueness

Morphology

observability = observable (semi-transparent) = observe + able + ity

Morphologically it is 'observable' + '-ity', but in engineering 'observability' has a precise technical meaning (inferring internal state from outputs) that goes beyond the everyday sense.

Etymology

The word observability comes from observe, meaning 'to watch', plus the ending -ability, meaning 'can be'. So observability is about how well you can tell what is happening inside a system from what you can watch or measure from the outside.
