Exploring Medical Language, 11th edition
Section 1: Chapter overview
- Chapter 1 is presented as the most important chapter in the text because it introduces the building blocks of medical language: word parts (word roots, prefixes, suffixes) and the combining vowels, plus the rules for combining them to form terms.
- This foundational knowledge is used in every subsequent chapter to analyze, build, define, and spell terms built from word parts.
- The chapter sets up a systematic approach that you will apply across topics in medical terminology.
Section 2: What is Medical Terminology?
- Definition: Specialized vocabulary used for communication among healthcare professionals.
- Learning objective (LO) context visible in the slides: Understanding the basics leads to the ability to analyze, build, define, and spell medical terms.

Section 3: Origins of Medical Language
- Greek and Latin word parts form the core of traditional medical terms.
- Eponyms: derived from the name of a person or place (e.g., Alzheimer’s disease is culturally associated with a person’s name).
- Acronyms: formed from the first letters of words in a phrase (e.g., AIDS = Acquired Immunodeficiency Syndrome).
- Modern language: terms derived from English language usage.
Section 4: Categories of Medical Terms
- Terms built from word parts: constructed using word roots, prefixes, suffixes, and combining vowels.
- Terms not built from word parts: include eponyms, acronyms, and terms derived from modern language or Greek/Latin forms that aren’t easily broken into word parts.
Section 5: Medical Terms Built from Word Parts
- Components:
- Word Roots (WR): fundamental meaning of a medical term.
- Suffixes (S): attached to the end to modify the meaning.
- Prefixes (P): attached to the beginning to modify the meaning.
- Combining Vowel (CV): used to ease pronunciation; usually an “o”.
- Visual cue: see “Combining Form” examples to connect a root with a vowel.
Section 6: The Four Word Parts (overview)
- Word Root (WR): fundamental meaning of a medical term.
- Suffix (S): attached to the end to modify meaning.
- Prefix (P): attached to the beginning to modify meaning.
- Combining Vowel (CV): used to ease pronunciation; usually an “o”.
Section 7: Combining Vowel Guidelines (Part 1 of 2)
- Rule 1: When connecting a word root and a suffix, a combining vowel is used if the suffix does not begin with a vowel.
- Rule 2: When connecting a word root and a suffix, a combining vowel is usually not used if the suffix begins with a vowel.
Section 8: Combining Vowel Guidelines (Part 2 of 2)
- Rule 3: When connecting two word roots, a combining vowel is usually used even if vowels are present at the junction.
- Rule 4: When connecting a prefix and a word root, a combining vowel is not used.
- Definition: Word root with its combining vowel attached.
- Example: arthr/o
- Illustration: Conveys how a root plus vowel forms a base for adding prefixes/suffixes.
- Example uses in practice: see later analyses.
Section 10: Techniques for Learning Medical Terms Built From Word Parts
- Three core techniques:
- Analyzing
- Defining
- Building
- These steps provide a repeatable workflow for every term you encounter.
Section 11: Analyzing (Worked Example: arthropathy)
- Step 1 (given): Word: arthropathy.
- Step 2: Divide the term into word parts with slashes: arthr/o/pathy.
- Step 3: Label each word part: WR = arthr, CV = o, S = pathy.
- Step 4: Write the combining form beneath the parts:
- WR = arthr
- CV = o
- S = pathy
- CF = arthr/o/pathy (the combining form is the root plus vowel with the suffix following)
- Visual aid from the slides: shows how to map morphology to labels.
Section 12: Defining (with arthro/pathy example)
- Apply word parts meanings to build the definition:
- Suffix -pathy = disease
- Word root arthr = joint
- Combined: arthr/o/pathy = disease of the joint
- Final definition: disease of the joint.
- This demonstrates how to move from parts to full meaning.
Section 13: Word Parts List (Key Roots and Suffixes)
- Word roots (examples):
- arthr = joint
- hepat = liver
- ven = vein
- oste = bone
- Suffixes (examples):
- -itis = inflammation
- -ic = pertaining to
- -ous = pertaining to
- -pathy = disease
- -megaly = enlargement
- Prefixes (examples):
- intra- = within
- sub- = under
- Combining vowel (special note):
Section 14: Building Medical Terms (how to assemble)
- Rule at the beginning of the definition: the suffix often gives the ending meaning; the stem defines the core concept.
- Procedure:
- Begin with the root(s)
- Add the combining vowel if needed to join roots or attach suffixes
- Attach prefixes if applicable
- End with the suffix to indicate the condition or procedure
- Example assembly: arthr/o/path/y (WR / CV / S)
- Notation: Write as ext{WR}
ightarrow ext{arthr}, ext{CV}
ightarrow o, ext{S}
ightarrow pathy - Final structure: arthr/o/path y (with proper spacing and punctuation in practice)
Section 15: Medical Terms NOT Built from Word Parts (Overview)
- Eponyms: e.g., Alzheimer disease
- Acronyms: e.g., AIDS (acquired immunodeficiency syndrome)
- Modern language terms: e.g., Complete blood count with differential
- Some terms arise from Greek and Latin roots that are not easily translated into a simple root/affix structure
- Some terms are specific field names that do not easily decompose (e.g., Orthopedics)
Section 16: Quick Reference Highlights (Summary of key points)
- Medical terminology relies on four primary word parts: WR, P, S, CV.
- Combining vowels (usually o) ease pronunciation and word-building, subject to rules about vowel-starting suffixes and cross-root connections.
- A systematic workflow (Analyzing → Defining → Building) helps interpret and construct terms.
- You should be able to identify root meanings, prefix/suffix modifications, and the overall term meaning from the parts.
- Not all medical terms are built from word parts; many are eponyms, acronyms, or modern-language terms.
Section 17: Quick practice prompts (self-check ideas)
- Given arthr/o/pathy, identify parts and define.
- List four word roots and their core meanings (arthr, hepat, ven, oste).
- Explain the combining vowel usage rules when attaching -itis and when attaching a suffix that begins with a vowel.
- Distinguish between terms built from word parts vs not built from word parts.
Section 18: Notation and symbols used in the chapter
- Word parts are often represented as:
- WR (Word Root), CV (Combining Vowel), P (Prefix), S (Suffix)
- Example representation for learning: arthr/o/pathy → WR / CV / S; CF stands for Combining Form
- Key example: arthr/o/pathy = disease of the joint
- Many slides include page references (e.g., 3, 4, 5, …) to guide study across the chapter; use them to locate corresponding content in the book.
Section 19: Practical implications and relevance
- Mastery of word parts enables efficient learning of new terms encountered in anatomy, physiology, pathology, and clinical practice.
- Understanding terminology supports clear communication among healthcare professionals and improves patient care by reducing misinterpretation.
- Recognizing term origins (Greek/Latin roots, eponyms, acronyms, modern language) helps with memorization and decoding unfamiliar terms in readings and exams.
Section 20: Mathematical or formula-like aspects (none explicit in content)
- The material is primarily lexical and morphological, with no explicit numerical formulas or statistical references.
- If you encounter numerical data in your coursework, prepare to translate any symbols or notation into standard mathematical forms, but chapter content here centers on morphemes and word-building rather than quantitative analysis.
Section 21: Key takeaways for exam prep
- Be able to identify and define each word part: WR, Prefix, Suffix, CV.
- Be fluent in applying the combining vowel rules when building terms from word parts.
- Practice with the arthr/o/pathy model to reinforce division into WR/CV/S and to connect parts to a definition.
- Memorize core word parts lists (examples above) and associate suffixes with their meanings.
- Recognize which terms are not built from word parts and understand why they fall outside the rule-set.
- Use the Analyze → Define → Build workflow as a repeatable study method for any new term.
Section 22: Quick reference for the pronunciation-friendly approach
- Use CVs to connect word parts to avoid awkward consonant clusters.
- When a suffix begins with a vowel, consider omitting the CV unless morphology dictates otherwise.
- When two roots are joined, include a CV to ease pronunciation unless a specific medical convention dictates otherwise.
