盲

The character can be interpreted in two ways:

1, Associative compound:

亡 — to lose

目 — eye

Meaning: “to lose one’s sight.”

2. Phono-semantic compound:

目 (eye) — semantic component

亡 — phonetic component, supplying the sound (맹 / máng)

Both interpretations reinforce the same semantic idea: loss of vision.

Semantic extensions from physical blindness to mental blindness:

- blind obedience;

- blind faith;

- lack of awareness.

Thus, 盲 frequently appears in abstract or moral discussions.

In Korean, many compounds use 盲 metaphorically to mean lack of awareness.

맹인 (盲人) — blind person

맹목 (盲目) — blindness; blind adherence

맹종 (盲從) — blind obedience

색맹 (色盲) — color blindness

In contemporary usage, respectful terminology for visually impaired persons is preferred.

The character still functions neutrally in compound words (e.g., 色盲, 文盲).

The metaphorical use is very productive in all three East Asian languages.
