Suffixes

Suffixes are word parts that are located at the end of words. Suffixes can alter the meaning of medical terms. It is important to spell and pronounce suffixes correctly.

Many suffixes in medical terms are common English-language suffixes. Suffixes are not always explicitly stated in the definition of a word. It is common that suffixes will not be explicitly stated when defining a medical term in the workplace. However, when transcribing or reading medical reports, the suffix is always clearly written. In order to properly spell and pronounce medical terms, it is helpful to learn the suffixes.

We will be seeing these suffixes mentioned again in this book, but they are presented here as a reference.
