Emily Dickinson Lexicon

THENCE, adv. [thens; Sax. thanan, thanon; G. dannen; from than, dann, then, supra. Then signifies properly place, or set time, from setting, and thence is derived from it. So the Germans say, von dannen, from thence.]

1. From that place. When you depart thence, shake off the dust of your feet. – Mark vi. It is more usual, though not necessary, to use from before thence. Then will I send and fetch thee from thence. – Gen. xxvii.
2. From that time. There shall be no more thence an infant of days. – Is. lxv.
3. For that reason. Not to sit idle with so great a gift / Useless, and thence ridiculous about him. – Milton.
