Word Building Rules in Medical Terminology

Additional words that complete the definition. The root word is the part of the medical term that gives the term its most basic or central meaning. An easy way to remember is that there is the central meaning and is usually found in the middle of the word. There are a lot of roots of words. This is because there is a root of word for every part of the body, everything that enters the body and everything that leaves the body. These are many roots of words. You may not be familiar with many combinations, suffixes, or prefixes, so let`s try to create a few terms by swapping the parts of the terms we`ve used in this lesson. You may need to provide the term for someone who specializes in the heart. You would use the root word “cardi-” and the suffix “-ologist” and get the medical term “cardiologist”. You may want to do the medical term for removing fluid from the intestine. They would use the combined form “entero-” with the suffix “-centesis” to form the term “enterocentesis”.

Before we start analyzing the rules, let`s do a quick language check that will help with pronunciation and spelling. The suffix of a medical term is found at the end of the term. The suffix is used to say later what happens to the root word. It can say what the root word does, what we do with it, or identify who does something with it. This is the part of the medical term that puts the end into action. Most medical terms contain a suffix. The combined form vowel is used to connect parts of words and facilitate pronunciation. The most common combined vowel is an “o”, but sometimes it is an “i” or an “e”. Although the suffix is found at the end of the word, the meaning of this affix is often placed at the beginning of the definition of the term. For example, for the word hepatitis, hepat is a root word meaning “the liver”, and it is a suffix meaning “inflammation”. The definition of hepatitis is inflammation of the liver. The last part of the word we need to discuss is the prefix.

The prefix is located at the beginning of the term and indicates a place, number, or time, or limits the meaning of the stem to a specific part. The prefix really helps to make the root word more specific. The prefix “peri-” means “surrounded or around”. This can be added to the term we just did, “cardiocentesis”, to form the term “pericardiocentesis”. In order to pronounce medical terms more easily when parts of the word are put together, the word roots may need to be changed to another form called the combined form. This usually involves adding the letter “o”, “i” or “a” to the end of the word root. Conversion of a stem to its combined form is required when you add a suffix or other word root that begins with a consonant. Thus, the combined forms for the roots of the word we have just discussed would be “cardio”, “gastro” and “entero”. Root words are the central part of the medical term that gives meaning to all terminology.

The prefix and suffix work together to provide additional information about the root word. Parts of words that do not correspond to linguistic rules Here is a list of common medical terminology: “Enter” is the root word that is combined with the vowel “o” for pronunciation to form the combinator form. “Entero” is a medical term that refers to the intestine. Now take the word “neoplasm.” Neo is a prefix that means new. -plasma is the root word, which means tissue. The neoplasm is therefore a new abnormal tissue growth. “-Oid” is the suffix meaning form or shape. A suffix is the part of a medical term that comes last. Medical terminology can be used to decipher drug names. Different parts of words are put together to achieve the goal of forming a medical term.

There are many prefixes, suffixes, and stems that can be used interchangeably to give a term a different meaning. Let`s take one last look at the terms we used as examples. The first term was “pericardiocentesis”. The term was formed to explain the removal of fluid that surrounds the heart. The other term was “gastroenterologist.” This term was formed to define a person who specializes or studies the stomach and intestines. The root word is in the middle of the term or at the beginning if there is no prefix.
