[a word of uncertain etymology, but probably from errant, which being at first applied to its proper signification to vagabonds, as an errant or arrant rogue, that is, a rambling rogue, lost, in time, its original signification, and being by its use understood to imply something bad, was applied at large to any thing that was mentioned with hatred or contempt.] Bad in high degree.
