Which term refers to a manner that is friendly and gracious?

The term "cordially" is used to describe a manner that is friendly and gracious. It implies warmth and goodwill in interactions, conveying a sense of welcome and kindness. When someone behaves cordially, they are showing friendliness, which is often essential in both personal and professional communication. This term sets the tone for positive engagement, making others feel comfortable and valued.

In contrast, the other terms do not reflect this sense of friendliness. "Vigorous" pertains to energy and strength, often in a physical context. "Conciliatory" suggests a tendency to make peace or mediate conflicts, which, while potentially friendly, does not inherently convey the warmth of being cordial. "Validate" refers to the act of confirming or supporting something, which does not relate to personal demeanor or graciousness. Understanding these distinctions helps clarify why "cordially" is the best choice to describe a friendly and gracious manner.
