Suffix Linking

Just to review, a suffix is added to the end of a word root or combining form to change the meaning of a medical word. If you change the suffix, you change the meaning of the word.

dermat/o (skin) + -logy (study of) = dermatology (study of the the skin)
dermat/o (skin) + -itis (inflammation) = dermatitis (inflammation of the skin)
dermat/o (skin) + -logist (specialist) = dermatologist (doctor who specializes in the skin)

Suffixes are also used to show singular and plural, as well as other parts of grammar.

Note: Suffixes that begin with a vowel are linked with a word root, suffixes that begin with a consonant are linked with a combining form

cardi/o (heart) + -megaly (enlarge) = cardiomegaly (enlargement of the heart)
suffix starts with a consonant “m”, so keep the “o” in the combining form

cardi/o (heart) + -ac (pertaining to) = cardiac (pertaining to the heart)
suffix starts with a vowel “a”, so drop the “o” in the combining form
