Emily Dickinson Lexicon

IN-TOX'I-CATE, v.t. [in and L. toxicum, which, Pliny informs us, is from taxa, a species of tree, in Greek, σμιλαξ. Lib. xvi, 10. Toxicum is from the Greek τοξον, a bow or an arrow; the barbarians used to poison their arrows, and hence toxicum in Latin came to signify poison.]

1. To inebriate; to make drunk; as with spirituous liquor. As with new wine intoxicated both / They swim in mirth. Milton.
2. To excite the spirits to a kind of delirium; to elate to enthusiasm, frenzy or madness. Success may sometimes intoxicate a man of sobriety. An enthusiast may be intoxicated with zeal.
