Character Breakdown

Understanding ~科

The suffix ~科 is commonly used in Japanese to denote a category or division within a larger group. It is frequently seen in medical contexts to indicate a department or specialty, such as 内科 (internal medicine) or 外科 (surgery). It is also used in academic settings to refer to departments or courses of study, like 経済学科 (economics department).

Usage in Medical and Academic Fields

In hospitals, ~科 specifies the medical specialty, helping patients identify the right department. In universities, it marks the academic division or major, guiding students and staff.

Common Collocations

  • 内科 (ないか): internal medicine department
  • 外科 (げか): surgical department
  • 経済学科 (けいざいがっか): economics department
  • 文学科 (ぶんがくか): literature department

Important Notes

When using ~科, it is attached directly to the root word indicating the field or category. It is not used alone but always as a suffix. Learners sometimes confuse ~科 with ~課 (section or division in a company), so be careful to distinguish these based on context.

Understanding ~科 helps learners navigate conversations about education, medicine, and classification systems in Japanese.
