What term describes a cheerful nature or spirit?

The term that best describes a cheerful nature or spirit is "jovial." This word originated from the Latin "Jovialis," which means "of Jupiter"—the Roman god associated with joy and merriment. When a person is characterized as jovial, it conveys an upbeat, light-hearted disposition that often includes a friendly or genial attitude toward others. In social settings, a jovial person tends to uplift the mood and foster a sense of camaraderie, making them enjoyable to be around.

The other choices do not relate to a cheerful nature. Dependence implies reliance on someone or something, which does not connote a spirited or happy disposition. Delusion refers to a false belief or judgment, which typically has negative connotations and is unrelated to cheerfulness. Aggravation denotes a state of being annoyed or irritated, which is the opposite of a cheerful spirit. Thus, "jovial" stands out as the term that accurately embodies a cheerful and spirited nature.
