Seeing and insight with 眼

The kanji 眼 has the concrete meaning of the eye, especially the eyeball or gaze as something fixed directly on what is being seen.

From that physical sense, 眼 naturally extends to sight, a person’s way of seeing, and then further to discernment and insight: not just having eyes, but seeing what matters.

Etymology

This kanji is a phono-semantic compound comprised of 目 (eye) as the semantic component and 艮 (stopping / turning back) as the phonetic component, giving the on-reading ガン. These invoke imagery of an eye fixed on something before it, holding it clearly in view.
