瘥

A phono-semantic compound consisting of:

疒 (sickness radical) — semantic component, indicating disease or illness;

差 (chā / chài) — phonetic component, providing the sound.

The structure conveys a condition related to illness, and specifically change in that condition—leading to meanings like recovery or disease.

Semantic development:

- illness (疒);

- change in condition;

- recovery from illness;

- disease itself (epidemic sense).

Thus, 瘥 encompasses both the state of illness and its resolution, depending on context.

In Korean, 瘥 is very uncommon, appearing mainly in classical texts or specialized contexts.

The dual meaning (disease vs recovery) reflects a broader concept of change in health condition.

In classical texts, 瘥 is often used to describe the moment of recovery rather than the process.

Compared to 癒, which emphasizes healing, 瘥 is more neutral and descriptive of state change.

The character is low-frequency and mostly of historical or literary interest today.

Among these, 瘥 uniquely captures the transition of illness, especially recovery.
