Chapter 2: Suffixes and Prefixes

Introduction to Suffixes and Prefixes

Understanding suffixes and prefixes is essential for building, analyzing, and interpreting medical terms. These word parts modify the meaning of root words and are fundamental in medical communication.

• Suffix: A syllable or group of syllables placed at the end of a word to alter its meaning or create a new word.

• Prefix: A syllable or group of syllables placed at the beginning of a word to modify its meaning.

• Both suffixes and prefixes are attached to root words or combining forms.

Suffixes in Medical Terminology

Suffixes are used to indicate various aspects of medical terms, such as grammatical function, pathological conditions, procedures, and more.

• Adjective Suffixes: Used to describe or modify nouns. Examples include -ic (pertaining to), -al (relating to), -ous (full of).

• Noun Suffixes: Indicate a person, place, thing, or concept. Examples include -ia (condition), -ism (state or condition), -ist (one who specializes).

• Diminutive Suffixes: Indicate smallness or lesser degree. Examples include -ule, -ole, -icle.

• Pathological Suffixes: Relate to disease or abnormal conditions. Examples include -itis (inflammation), -osis (abnormal condition), -pathy (disease).

• Surgical and Diagnostic Suffixes: Indicate procedures or tests. Examples include -ectomy (removal), -scopy (visual examination), -graphy (recording).

Example: The term appendectomy combines the root append- (appendix) with the suffix -ectomy (removal), meaning surgical removal of the appendix.

Prefixes in Medical Terminology

Prefixes modify the meaning of medical terms by indicating location, number, time, or other characteristics.

• Common Prefixes: Examples include pre- (before), post- (after), anti- (against), hyper- (excessive), hypo- (below normal).

• Prefixes with Multiple Meanings: Some prefixes can have more than one meaning depending on context. Example: peri- can mean "around" or "about".

• Prefixes of Position or Placement: Indicate location or direction. Examples: sub- (under), super- (above), inter- (between).

• Prefixes of Numbers and Amounts: Indicate quantity. Examples: bi- (two), tri- (three), poly- (many), mono- (one).

Example: The term polyuria combines the prefix poly- (many) with the root -uria (urine), meaning excessive urination.

Analyzing, Building, Spelling, and Pronouncing Medical Words

Mastery of suffixes and prefixes enables students to analyze, construct, spell, and pronounce medical terms accurately.

• Break down medical terms into their component parts: prefix, root, suffix.

• Apply rules for combining forms and word parts.

• Practice spelling and pronunciation for clarity in medical communication.

Example: The term hypoglycemia is composed of hypo- (below), glyc- (sugar), and -emia (blood condition), meaning low blood sugar.
