MedTerm Overview - Prefix, Suffix, Combining Words Flashcards
Four word parts
- Word root 2. Prefix 3. Suffix 4. Combining form
Word root
the word part that is the core of the word. eg. play/er, play is the word root; arthr/itis, arthr (which means joint) is the word root hepat/itis, hepat (which means liver) is the word Root
Suffix
word part attached to the end of the word rot to modify its meaning eg. play/er, -er is the suffix hepat/ic, -ic (which means pertaining to) is the suffix Hepat/itis, -itis (which mean inflammation) is the suffix
Prefix
word part attached to the beginning of a word to modify its meaning eg. re/play, re- is the prefix sub/hepat/ic, sub- (which means under) is the prefix intra/ven/ous, intra- (which means within) is the prefix, ven (which means vein) is the word root, -ous (which means pertaining to) is the suffix
Combining Form
a word root with the combining vowel attached, separated by a vertical slash eg. arthr/o oste/o
Combining Vowel
the word part, usually an O, used to ease pronunciation eg. oste/o/arthr/itis
Four guidelines for using combining vowels
- When combining a word root and a suffix , a combining vowel is used if the suffix does not begin with a vowel 2. When connecting a word and a suffix, a combining vowel is usually not used if the suffix begins with a vowel 3. When connecting two word roots, a combining vowel is usually used even if the vowels are present at the junction 4. When connecting a prefix and a word root, a combining vowel is not used
