Emily Dickinson Lexicon

BOUND, pp. [and pret. of Bind.]

1. As a participle, made fast by a band, or by chains or fetters; obliged by moral ties; confined; restrained.
2. As a participle, or perhaps more properly as adjective, destined; tending; going, or intending to go; with to or for; as, a ship is bound to Cadiz, or for Cadiz. The application of this word, in this use, is taken from the orders given for the government of the voyage, implying obligation, or from tending, stretching. So destined implies being bound. Bound is used in composition, as in ice-bound, wind-bound, when a ship is confined or prevented from sailing by ice or by contrary winds.
