double-cross
UK: ˌdʌb.əlˈkrɒs | US: ˌdʌb.əlˈkrɔːs
vt. to betray or deceive someone after gaining their trust
n. an act of betrayal or deception
The term "double-cross" originated in the early 19th century, initially used in criminal slang. The "cross" refers to cheating or betrayal, while "double" intensifies the act, implying a second layer of deception. Historically, it may derive from the practice of crossing out a name twice to mark a traitor or from a double reversal of allegiance. The word vividly captures the idea of being deceived after trust is established.
