hang

   to kill by breaking the neck through suspension

   Formerly, it meant death by crucifixion, but it is now standard English in the present sense, the past sense being hanged not hung:

    'No, Grace, we don't hang them any more.' 'Not even murderers?' 'Specially not them.' (N. Mitford, 1960)

   A hang-fair was an execution by hanging in public and a hanging judge was one who readily sentenced people to death:

    The innkeeper supposed her some harumskarum young woman who had come to attend the 'hang-fair' next day. (Hardy, 1888)

    He's got one or two unlikely convictions out of them. A hanging judge, some people said. (Christie, 1939)
