PLEASANT

Pleas"ant, a. Etym: [F. plaisant. See Please.]

1. Pleasing; grateful to the mind or to the senses; agreeable; as, a pleasant journey; pleasant weather. Behold, how good and pleasant it is for brethren to dwell together in unity! Ps. cxxxiii. 1.

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

Syn.

– Pleasing; gratifying; agreeable; cheerful; good-humored; enlivening; gay; lively; merry; sportive; humorous; jocose; amusing; witty.

– 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.

Pleas"ant, n.

Definition: A wit; a humorist; a buffoon. [Obs.]
