A root is a word part that gives the essential meaning of the word

Root words may need a combing vowel, usually an “o” which usually makes the word easier to pronounce“i” and “e’ may also be used

Root words

The root word plus the combining vowel makes up the combining formOften written (and pronounced)

Ren/oGastr/oCardi/o

Rule 1:When the suffix or next word part begins with

a consonant use a combining vowelArthr/o and –scope = Arthroscope

Rule 2:Don’t need a combining vowel if the suffix

starts with a vowelGastr/o and –itis = gastritis

Rule 3:A combining vowel is used when two or more

root words are joined togetherGastr/o and enter/o and –it is = gastroenteritis

GastroenteritsNasolabial Colorectal

Most medical root words or combining forms usually describe a part of the body
