Use "serpentize" in a sentence
"The scene is a little changed for the worse: the lovely landscape is now one undistinguished waste of snow, only a little diversified by the great variety of ever-greens in the woods: the romantic winding path down the side of the hill to our farm, on which we used to amuse ourselves with seeing the beaux serpentize, is now a confused, frightful, rugged precipice, which one trembles at the idea of ascending."
