Which word refers to someone who is acutely insightful and wise?

The word "sagacious" specifically conveys a depth of wisdom and insight that goes beyond mere perception or intuition. It describes someone who not only understands complex situations but also possesses the profound judgment and experience to make sound decisions. This term often implies an ability to discern and interpret subtle nuances in various contexts, showing a high level of discernment and wisdom that is recognized and respected.

While "perceptive," "intuitive," and "astute" all relate to insightfulness and sharp awareness, they do not capture the full depth of wisdom implied by "sagacious." "Perceptive" emphasizes the ability to notice and interpret information quickly and accurately but doesn't necessarily entail a wealth of wisdom. "Intuitive" suggests a natural ability to understand or know something without the need for conscious reasoning, which does not require the same level of experience or judgment. "Astute" refers to being clever and able to assess situations to gain an advantage, indicating sharpness and shrewdness, but again lacks the overarching wisdom connoted by "sagacious." Thus, "sagacious" distinctly embodies a combination of insight, wisdom, and sound judgment, making it the correct choice.
