What does "pleasant" mean?

Pleasant: 2. Cheerful; enlivening; gay; sprightly; humorous; sportive; as, pleasant company; a pleasant fellow. From grave to light, from pleasant to serve. Dryden. -- 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.
