v. (動詞)

• bound用作動詞作“跳躍”解時,指水平曏前地、快速連續地跳躍,強調由此獲得的沖力,暗含精神上的輕松與活力之意。

• bound用作形容詞時與bind的過去分詞同形,基本意思是“被綑綁的,被束縛的”,常引申表示“受約束的”“有義務的”,指有法律責任或有義務做某事
• bound還可作“一定的,必定的”“去,準備去”解,衹用作表語。作“一定的,必定的”解時,其後常接動詞不定式，不跟to短語；作“去；準備去”解時常跟for短語表示目的地。
• bound後可接不定式，原在英國表示“將不得不……”，在美國表示“決意……”解。如今，兩國人都將其解釋爲“一定將……”。It is bound to rain. 一定將會下雨。
