Amiable, good-natured, obliging and complaisant all mean having or manifesting the desire or disposition to please. All may refer either to moods or to temperaments.
Amiable usually implies friendliness, affability, or kindliness, qualities that inspire liking.

Often, however, the word suggests little more than a sweet temper.
- preferred an amiable softness to a tragic intensity
Occasionally it additionally connotes lack of firmness or strength.
- she suddenly married a poor, good-for-nothing, amiable fellow
Good-natured implies a disposition not only to please but to be pleased; consequently it often connotes undue compliance or indifference to imposition.

Obliging stresses a readiness to be helpful, or to accommodate to the wishes of others.

Complaisant implies a courteous or sometimes a weakly amiable desire to please or to be agreeable.
