adj. having or showing a clear and deep understanding of people or situations

The word "insightful" combines "in-" (into), "sight" (vision), and "-ful" (full of). "Sight" originates from Old English sihþ (seeing), while "-ful" is a productive suffix in English denoting abundance. The compound suggests "full of seeing into" something, metaphorically extending to mental perception. The term evolved in the 19th century to describe intellectual depth, reflecting the literal idea of "seeing inward" to grasp hidden truths.
