The combining form –genic is used like a suffix with a variety of meanings, all essentially meaning “of or related to production or generation.” In some instances, the initial element specifies the thing being produced. For instance, ulcerogenic means “ulcer-producing.” In others, the initial element specifies the location or generator of production, such as costogenic, meaning “arising from a rib.” The form –genic is often used in scientific terms, especially in biology and medicine.

The form –genic comes from the combination of two forms, –gen and –ic. The form –gen means “that which produces,” from Greek –�����ŧ��, meaning “born” or “produced.” The suffix –ic means “having some characteristics of,” from Greek –ikos. The Latin translation and cognate of –�����ŧ�� is ����ٳܲ�, meaning “born,” which is the source of natal, native, and nature. Find out how these terms derive from ����ٳܲ� at our entry for each word.
