Which term describes someone who is lively or full of spirit?

The term that describes someone who is lively or full of spirit is "vivacious." This word is often used to characterize people, especially women, who exhibit an energetic and spirited personality. A vivacious individual brings enthusiasm, charm, and brightness to their interactions, making them engaging and pleasant to be around.

In contrast, "voracious" refers to a strong desire or appetite, typically for food or knowledge, but does not convey the same lively spirit. "Xenophobia" describes a fear or prejudice against people from other countries, which is unrelated to personality traits. "Zealot" denotes someone who is fanatical and uncompromising in pursuit of their beliefs, which does not inherently imply liveliness or spiritedness. Thus, "vivacious" is the most fitting term in the context of someone who embodies liveliness and spirit.
