The 科 suffix and the many faces of 薬
Five words here are built the same way: field + 科, the productive suffix for medical specialties — 皮膚科, 産婦人科, 精神科, 歯科, 眼科 — a pattern that continues outside this list with 外科 (surgery) and 内科 (internal medicine). Separately, watch how the root 薬 (medicine) shifts meaning depending on what follows it: 薬剤 is the clinical term for a formulated drug, 薬品 leans toward medicines as manufactured products, 薬物 often carries a narcotics or controlled-substance connotation (as in 薬物乱用, drug abuse), and 薬害 flips the sense entirely to mean harm caused by a drug rather than its benefit. The kanji 症 does similar work for conditions, marking something as a diagnosed state rather than a vague complaint in 感染症, 既往症, and 症候.
Frequently Asked Questions
What is the difference between 処置, 処方, and 処方箋?
処置 is a medical procedure or action actually performed on a patient, such as 応急処置 (first aid). 処方 specifically means prescribing medication — the doctor's decision about which drugs to give. 処方箋 is the physical prescription slip handed to the patient, built from 処方 plus 箋 (a written note or slip).
疾患, 病状, and 症候 all seem to mean 'illness' — how do they differ?
疾患 is the general clinical term for a disease or disorder itself, used in formal writing the way English uses 'condition' (e.g. 慢性疾患, a chronic disease). 病状 refers to the current state or progression of an illness a patient already has. 症候 means the outward signs or symptoms that indicate a disease is present, close to English 'symptom' — it is also the root of 症候群 (syndrome), a common word built the same way outside this list.
