Usage

What does -iasis mean? The form -iasis is a suffix used to denote the names of disease or other nouns of state or process. It is often used in medical terms, especially in pathology.The form -iasis comes from Greek -íasis, denoting the names of diseases. It is a common misconception that -íasis comes from the verb iâsthai, meaning “to heal,” which is the source of the combining forms -iatry and iatro-. Instead, -iasis is derived from the Greek verb ending -áein (also ân), with the initial -i- used as a connecting vowel, featuring the noun-forming suffix -sis.
