Understanding the Word Lifeless

The question asks us to find the appropriate antonym for the word "lifeless" in the sentence "His gray, lifeless eyes were sunken." The word "lifeless" is used here to describe eyes that lack expression, energy, or vitality. It suggests dullness, inactivity, or a lack of spirit.

To find the antonym, we need a word that means the opposite of lacking life, energy, or spirit.

Analyzing Antonym Options

Let's look at the meaning of each provided option:

• Extinct: This word typically means having no living members; having died out (referring to species). While it relates to the absence of life, it's usually not used to describe the state of being dull or lacking energy in something that is otherwise alive or expected to be active, like eyes.
• Lapsed: This word means no longer valid; having passed into or relapsed into a worse state or condition. This is unrelated to the concept of being "lifeless" in terms of vitality or energy.
• Vibrant: This word means full of energy and enthusiasm; pulsating with vigor and energy. It can also refer to colors that are bright and striking. This meaning is a direct opposite of "lifeless" when describing something lacking energy, spirit, or vividness.
• Pointed: This word means having a sharp end, or expressing sharp criticism. This is unrelated to the meaning of "lifeless" in this context.

Why Vibrant is the Antonym of Lifeless

Comparing the meanings, "vibrant" stands out as the most appropriate antonym for "lifeless". Where "lifeless" describes something lacking energy, spirit, or vividness, "vibrant" describes something full of energy, spirit, and vividness. Therefore, if eyes are not "lifeless" (dull, lacking spirit), they might be described as "vibrant" (full of energy, spirit, and expression).

Thus, the word "vibrant" is the antonym of "lifeless" in this context.
