Basic Elements of a Medical Word 1. Word Root 2. Combining Form ( جزء من كلمة قابل للمزج مع كلمة أخرى) 3. Suffix 4. Prefix These four parts of a word are known as ELEMENTS.

Word Root Main part or foundation of a word. All words have at least one word root. A word root may be used alone or combined with other elements to form a complete word. IE: SPEAK (word root) + ER (suffix) = SPEAKER (complete word)

Word Root The word root usually refers to a body part. Some root words are derived from the Latin or Greek language.

Word Root Examples “dent” means tooth “dermat” means skin “cardi” means heart “gastr” means stomach “pancreat” means pancreas

Combining Forms Correct pronunciation of medical words is important. In order to make the pronunciation of word roots easier, sometimes it is necessary to insert a vowel after the root. The combination of a word root and a vowel is known as a COMBINING FORM.

Combining Forms Combining forms consist of a combining vowel. The combining vowel is usually an “o”, but others may be used. IE: gastr / o pronounced GASTRO. Word root Combining vowel

Word-Building System By understanding the meanings of word roots, one can determine the meaning of complex medical terms by putting together the smaller parts.

Leukocytopenia Word Roots: Leuk / (white) cyt / (cell) Combining Vowel / o / Suffix: / penia (decrease)

A combining vowel is used between a word root and a suffix that begins with a consonant (not a vowel). This is to make pronunciation easier. Word root: scler / (hardening) Suffix: / derma (skin) Term: Scler / o / derma (hardening of the skin) Combining vowel

Suffixes A suffix is a word element placed at the end of a word or word root that changes the meaning of the word. In the terms tonsill/itis, and tonsill/ectomy, the suffixes are – -itis (inflammation) – and -ectomy (excision, removal). Changing the suffix changes the meaning of the word. In medical terminology, a suffix usually indicates a procedure, condition, disease, or part of speech. Many suffixes are derived from Greek or Latin words

Review A combining vowel IS used to link one root to another root, and before a suffix that begins with a consonant. A combining vowel IS NOT used before a suffix that begins with a vowel.

Prefixes A prefix is a word element attached to the beginning of a word or word root. Adding or changing a prefix changes the meaning of the word. The prefix usually indicates a number, time, position, or direction. Many of the same prefixes found in medical terminology are also found in the English language

Hypoinsulinemia Hypo / insulin / emia Prefix Word root suffix LOW INSULIN BLOOD Notice that there is no combining vowel in this word because the prefix ends with a vowel and the suffix begins with a vowel.

Defining Medical Words Here are the three basic rules for defining medical words using the example term gastroenteritis. Rule #1 – Define the suffix, or last part of the word. In this case, -itis, which means inflammation. Rule #2 – Define the first part of the word (which may be a word root, combining form, or prefix). In this case, the combining form gastr/o means stomach. Rule #3 – Define the middle parts of the word. In this case, enter/ means intestine.

Defining Medical Words When you analyze gastroenteritis following the three previous rules, the meaning is revealed as: 1. inflammation (of) 2. stomach (and) 3. intestine Thus, the definition of gastroenteritis is “inflammation (of) stomach (and) intestine.”

Building Medical Words There are three basic rules for building medical words. Rule #1 – A word root links a suffix that begins with a vowel. Rule #2 – A combining form (root + o) links a suffix that begins with a consonant. Rule #3 – Use a combining form to link a root to another root to form a compound word.
