Rasante \Ra`sante"\, a. [F., p. pr. of raser to graze.] (Fort.)
   Sweeping; grazing; -- applied to a style of fortification in
   which the command of the works over each other, and over the
   country, is kept very low, in order that the shot may more
   effectually sweep or graze the ground before them. --H. L.
   Scott.
