醫

It is a compound character, formed from:

酉 (yu, “wine, ferment,” functioning as the semantic element);

殹 (ye, “groaning sound when ill,” as the phonetic element).

It denotes “doctor,” “medicine,” and related ideas such as 의사 (醫師, doctor) and 의약품 (醫藥品, medicine, medical drugs).

Common compounds:

의사 (醫師) – doctor;

의원 (醫員) – medical practitioner / hospital;

의약 (醫藥) – medicine, medical treatment;

의학 (醫學) – medical science;

수의사 (獸醫師) – veterinarian.

Still very productive in modern compounds, mainly academic and professional contexts.

In everyday usage, appears most often in 의사 and 의원.
