What does malleability mean?
Malleability is a noun meaning the quality of being easy to shape, bend, or hammer without breaking, a property especially associated with metals such as gold, copper, and aluminium. The word can also describe a person or institution that adapts readily to new conditions, influences, or political pressures. In physical sciences and engineering, malleability is contrasted with brittleness and describes how a material responds to compression or shaping forces. In social and political discussion, it may carry a more critical sense, suggesting that someone is flexible but perhaps too easily influenced or inconsistent in their principles. The word derives from the same Latin root as “malleable,” meaning hammerable or workable under a hammer, and is useful when describing both the physical properties of materials and the changing character of people or organizations.

"Her political malleability allowed her to work effectively with changing administrations."
The plural is rare and is used mainly in technical or analytical writing.
"The researchers compared the malleabilities of several candidate materials."
From the Latin for hammer, malleability is the hidden superpower of metals—and, figuratively, of people who can be shaped by experience.

Where does malleability come from?
The word comes through French from the Latin adjective malleus, meaning “hammer,” with the suffix -ability added to form the noun. Latin malleus also gave rise to “malleable” and related English words concerning hammering or shaping. Over time, the term broadened from a description of metals to a figurative description of people, policies, and institutions that can be adapted or influenced.
