What is the opposite of enervate?

The correct choice is the term that suggests a restoration of strength or energy. When we look at the meaning of "enervate," it refers to draining someone of energy or vitality, weakening their strength or effectiveness. In contrast, to revitalize means to imbue someone or something with new energy and life. This term captures the idea of strengthening and rejuvenating, which is the opposite of what enervate conveys.

While the other options also relate to weakening or diminishing strength, they do not capture the essence of restoring vitality. "Weaken," "debilitate," and "reduce" all imply a loss of strength or effectiveness, aligning more closely with the definition of enervate rather than providing a contrasting meaning. In this way, "revitalize" stands out as the correct antonym, representing a complete reversal of enervation.
