The word "和蔼可亲" is formed by combining the two-character phrase "和蔼", meaning gentle and kind, with "可亲", meaning amiable or approachable. "和" contributes the sense of harmony, "蔼" adds friendliness, "可" introduces the idea of being worthy of, and "亲" provides the notion of closeness, resulting in a compound that intensifies the description of a person's agreeable nature.
