What does modifiability mean?
Modifiability is the condition of being changeable, adjustable, or open to amendment. The word is especially common in academic, legal, philosophical, and technical discussion, where writers may ask whether a rule, theory, system, agreement, or assertion can be altered. A thing can be modifiable without being easy to modify: formal procedures, costs, or institutional constraints may make change difficult even when change is possible. The noun differs from modification, which names an actual change, and from modifiable, which describes something capable of being changed. Modifiability is also associated with adaptability, but the words are not exact equivalents; adaptability more often suggests responding successfully to new conditions, whereas modifiability concerns whether modification is possible. The term is much less common in everyday conversation than its simpler relatives modify and change.

Where does modifiability come from?
Modifiability was formed by adding the suffix -ability to modify. The verb modify comes through Old French modifier from Latin modificare, a compound of modus, meaning measure or manner, and facere, meaning to make. The same Latin foundation also produced modification and modifier, while modifiable follows the same Latin root with the suffix -able.
