Bashfulness is a shrinking from notice without assignable reason. Coyness is a half encouragement, half avoidance of offered attention, and may be real or affected. Diffidence is self-distrust; modesty, a humble estimate of oneself in comparison with others, or with the demands of some undertaking. Modesty has also the specific meaning of a sensitive shrinking from anything indelicate. Shyness is a tendency to shrink from observation; timidity, a distinct fear of criticism, error, or failure. Reserve is the holding oneself aloof from others, or holding back one's feelings from expression, or one's affairs from communication to others.
