In Jewish folklore, a golem (גולם) is an animated anthropomorphic being created entirely from inanimate matter. In modern Hebrew the word golem literally means “pupa”, but can also mean “fool”, “dumb”, or even “stupid”.

Writing the word emet (אמת, “truth” in the Hebrew language) on its forehead activates the golem. A golem could then be deactivated by removing the aleph (א) in emet, thus changing the inscription from ‘truth’ to ‘death’ met (מת, “dead”).
