"She begins by sculpting with malleable French clays to create her figures, then she makes a mold." — Fina Badolato, The Rochester (New York) Democrat and Chronicle, 13 Feb. 2022

Language is constantly evolving; the meanings, spellings, and pronunciations of words are reshaped over time. Take, for example, the Latin noun malleus, meaning "hammer." This word was adapted to create the Latin verb malleare, meaning "to hammer," which led eventually to the English adjective malleable. Malleable originally meant "capable of being extended or shaped by beating with a hammer," and over time adopted the broader sense "capable of being shaped, altered, or controlled." If you guessed that maul and mallet, other English words for specific types of hammers, are also modeled from malleus, you have hit the nail on the head.
