   Usage: Pleasant, Pleasing, Agreeable. Agreeable is
          applied to that which agrees with, or is in harmony
          with, one's tastes, character, etc. Pleasant and
          pleasing denote a stronger degree of the agreeable.
          Pleasant refers rather to the state or condition;
          pleasing, to the act or effect. Where they are applied
          to the same object, pleasing is more energetic than
          pleasant; as, she is always pleasant and always
          pleasing. The distinction, however, is not radical and
          not rightly observed.
          [1913 Webster]
