The combining form –genous is used like a suffix meaning “of or related to that which produces.” It is often used in scientific terms, especially in biology.

The form –genous comes a combination of two combining forms, –gen and –ous. The form –gen means “that which produces,” from Greek –�����ŧ��, meaning “born” or “produced.” The form –ous is a suffix used to form adjectives, from Latin –ō���ܲ�. 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.
