double-faced

The word "double-faced" is a transparent English compound. Its first element, "double," originates from Latin duplus, meaning "twofold," which itself derives from the Proto-Indo-European root dwo-, meaning "two." The second element, "face," traces back to Latin facies, referring to form or appearance. The compound literally means "having two faces," a concept powerfully illustrated by the Roman god Janus, who was depicted with two faces looking in opposite directions. Over time, this literal sense evolved into the modern abstract meaning of deceitfulness or hypocrisy, describing a person who presents one favorable appearance while concealing another, contrary nature.

Structure: double (twofold) + face (front part of the head) + ed (adjective suffix) - double: From Latin duplus (twofold, double). In this compound, it functions as a modifier meaning "having two." - face: From Old French face, from Latin facies (form, appearance, face).
