Etymology
Origin of malleable
1350–1400; Middle English malliable < Medieval Latin malleābilis, equivalent to malle ( āre ) to hammer (derivative of Latin malleus hammer) + -ābilis -able
Explanation
A malleable metal is able to be pounded or pressed into various shapes, and a malleable personality is capable of being changed or trained. It's easier to learn when you're young and malleable. Just as there are substances that are malleable, including clay and some metals, there are also ductile metals that can be hammered out into wire or thread; gold, silver, and platinum are examples. The adjective malleable dates back to Middle English, from Old French, from Medieval Latin malleābilis, from malleāre, "to hammer."
