Where it comes from
From Middle English wassail, from Old Norse ves heill (“be healthy!”), from the imperative of vesa (“to be”) + heill (“healthy”). The earliest documented use of the term is from the first part of the 12th century CE, in Geoffroy of Monmouth's Historia Regum Britanniae (see page's citations).
