Medical terminologyMedical terminology• Each health care specialty has its own

terminology and abbreviations

• Health care professionals become so used

to the language of their specialty they

forget others don’t understand these terms

When not to use medical When not to use medical terminologyterminology

Medical conditions, diagnoses, treatments and terms should always be explained in lay person’s language when talking to patients, family and community members

Be aware of the client’s literacy level and language of origin

Building blocks of medical Building blocks of medical languagelanguage

Medical terms are made up of several

parts – elements - that can be combined

to make many different words

Learning the meaning of these elements

helps understand many medical terms

Prefix RootCombining

Vowel Suffix

The RootThe Root• The root is the part of the medical

term that gives the main meaning• It usually refers to a structure and/or

function of the body• Roots are usually Latin or Greek in

origin• All medical terms have at least one

root

80 slides total 9

Combining formsCombining formsCombining forms consist of roots plus a

vowel, usually the letter “o”In the dictionary, the vowel is separated

from the root with a slash mark, example: Gastr/o - stomach Enter/o – small intestine Cardi/o - heart

80 slides total 10

Combining vowelCombining vowelThe letter “o” is called the

combining vowelIt links the root to the “suffix,” the

next element in the medical termUsed if the suffix begins with a

consonant.Not needed if the suffix begins with

a vowel

Roots and combining formsRoots and combining formsThere are thousands of roots and

combining forms that make up medical language

You need to learn the roots and combining forms used in general medical terminology and what is specific to maternity care

80 slides total 17

Combining formsCombining forms

The letter “o” is called the combining vowel

It links the root to the “suffix,” the next element in the medical term, if the suffix begins with a consonant.

The combining form is always used when linking two roots, even if the second one starts with a vowel.

80 slides total 18

SuffixesSuffixes

Suffixes are word elements that are

attached to the end of roots and

combining forms to add to or change

their meaning

All medical terms have a suffix

80 slides total 19

SuffixesSuffixes

Each suffix can be added to many

roots

itis = inflammation

appendicitis = inflamed

appendix

arthritis = inflamed joint

80 slides total 20

SuffixesSuffixes

The combining vowel is used between the root and the suffix when the suffix begins with a consonant:

Example: cardi + o + megaly = cardiomegaly

cardiomegaly = enlarged heart

cardi = heart, megaly = enlarged

80 slides total 21

SuffixesSuffixes

When the suffix begins with a vowel, there is no need for a combining vowel between the root and the suffix

The suffix is attached to the root wordExample: gastr + itis = gastritisgastritis = inflammation of the

stomachgastr = stomach, itis = inflammation

SuffixesSuffixesSome common meanings of suffixes:• Pathological (disease) conditions• Diagnostic procedures• Surgical procedures• Pertaining to• Produced by• Resembling

80 slides total 23

SuffixesSuffixes

• When suffixes are listed in medical dictionaries or word lists, they are listed alphabetically

• The word is preceded by a dash and identified as a word element

• The dash indicates something precedes it

• Dictionary entries will give the language of origin, usually Latin or Greek

PrefixesPrefixesPrefixes are word elements that are

attached to the beginning of roots and combining forms to add to or change their meaning

Many (but not all) medical terms have a prefix

Common meanings of prefixes:Location

80 slides total 31

PrefixesPrefixes

The same prefixes can be attached to many root words, resulting in thousands of variations

The prefix “hyper” means “abnormally increased or excessive”

Hyperacid = excessively acidicHyperactive = abnormally activeHypertension = persistently high blood pressure

80 slides total 32

PrefixesPrefixesPrefixes can dramatically change the

meaning of a wordExample: “systole” means “contraction

of the heart”The one letter prefix “a” means

“without”“Asystole” means “no contractions of

the heart” -- Just one letter makes the difference between life and death!

Correct spelling is critical in health care

dictionaries and word lists, they are located alphabetically followed by a dash and identified as a word element
