Wanion , noun
[Probably for Old English waniand waning, present participle of wanien; hence, used of the waning of the moon, supposed to be an unlucky time. See Wane.]
A word of uncertain signification, used only in the phrase with a wanion, apparently equivalent to with a vengeance, with a plague, or with misfortune. [Obsolete] — B. Jonson. Latimer
