Synonyms
— To confuse; confound; disconcert; shame.
— To Abash, Confuse, Confound. Abash is a stronger word than confuse, but not so strong as confound. We are abashed when struck either with sudden shame or with a humbling sense of inferiority; as, Peter was abashed in the presence of those who are greatly his superiors. We are confused when, from some unexpected or startling occurrence, we lose clearness of thought and self-possession. Thus, a witness is often confused by a severe cross-examination; a timid person is apt to be confused in entering a room full of strangers. We are confounded when our minds are overwhelmed, as it were, by something wholly unexpected, amazing, dreadful, etc., so that we have nothing to say. Thus, a criminal is usually confounded at the discovery of his guilt. Satan stood Awhile as mute, confounded what to say. Milton.
