Etymology
In Jewish and medieval folklore, a golem is an animated anthropomorphic being, magically created from inanimate matter. The word was used to mean an amorphous, unformed material (usually out of stone and clay) in Psalms and medieval writing. Adam, the first man created by God in the Holy Bible, was a golem since he was created from dust and sand. Having a golem servant was seen as the ultimate symbol of wisdom and holiness, with stories of prominent Rabbis owning golems throughout the middle ages. In modern times, the word golem, sometimes pronounced goilem in Yiddish, has come to mean one who is slow, clumsy, and generally dimwitted.
