rebuff, refuse, reject, repel, repulse (vv.)
At least one and sometimes more than one of these words can serve to define each of the others, and all are at least partial synonyms. To rebuff is to check or reject, to refuse bluntly, to snub, as in She rebuffed his familiarity with a haughty stare; to repulse is to reject rudely, to drive back, as in She repulsed him with a sharp comment; to repel is to turn away or turn back, to decline (a proposal), or to disgust and so drive away, as in His proposal of marriage repelled her, so she repelled it; to reject is to say no to or spurn, to turn back, as in When he proposed, she rejected him out of hand; and to refuse is to decline, to say no, not to accept, as in He refused to accept her answer as final.
