   Easily confused or put out of countenance; diffident;

   [1913 Webster]

   Note: Shamefaced was once shamefast, shamefacedness was
         shamefastness, like steadfast and steadfastness; but
         the ordinary manifestations of shame being by the face,
         have brought it to its present orthography. --Trench.
