Suffix ? A suffix is a word ending that modifies a root. A suffix may indicate that the word is a noun or an adjective and often determines how the definition of the word will begin. For example, using the root myel/o , meaning “ bone marrow, ” the adjective ending - oid forms the word myeloid , which means “ like or pertaining to bone marrow. ” The ending - oma produces myeloma , which is a tumor of the bone marrow. Adding another root, gen , which represents genesis or origin, and the adjective ending - ous forms the word myelogenous , meaning “ originating in bone marrow. ” Classification Table1:Suffixes that mean "condition of" sustained muscle contraction tetany -y hardening sclerosis -sis Alcoholic Intoxication alcoholism -ism insufficient amount of oxygen hypoxia - ia Definition of example Example Suffix The medical science that deals with the origin, diagnosis, prevention, and treatment of mental disorders psychiatry medical specialty - iatry A medical specialty concerned with maintaining health and providing medical care to children from birth to adolescence pediatrics medical specialty - iatrics A surgical specialty which utilizes medical, surgical, and physical methods to treat and correct deformities orthopedics medical specialty - ics Study of function in a anism physiology study of -logy specialist in the study and treatment of the heart cardiologist specialist in a field of study - ist practitioner of medicine physician specialist in a field of study - ian Definition of example Example Meaning Suffix Table2:Suffixes for medical specialties Table 3:Suffixes for a group of substance 磷酸盐 phosphate salt -ate 葡萄糖 glucose sugar - ose 山梨醇 sorbitol alcohol -ol 脂肪瘤 lipoma cancer,tumor -oma 氧化酶 oxidase enzyme - ase 白细胞 leukocyte cell - cyte Chinese meaning Example Meaning Suffix Table 4:Suffixes that mean "pertaining to" or "resembling" per
