Word Origin & Etymology

Coined in mid-20th-century American slang from the adjective 'weird' plus the informal nominal suffix '-o'. The root 'weird' ultimately derives from Old English 'wyrd' (fate or destiny), which shifted toward 'uncanny' or 'strange' through the portrayal of the Weird Sisters in Shakespeare's Macbeth.
