Constructed medical terms:Many medical terms are ‘constructed’ from a combination of
word parts… prefixes, Greek or Roman root words, and suffixes. Determine the meaning of the whole word by first deciphering the meaning of the suffix, then the prefix, and
finally the root word. Then combine the 3 parts.
MICRO / SCOP / ICPrefix meaning ‘small’ / root word meaning ‘viewing instrument’ / suffix meaning ‘pertaining to’
When you start with a root word and add a suffix that starts with a consonant OR another root word, then you have to connect the two word parts with a vowel. This is called a ‘combining vowel’, and is usually an ‘o, i, or e’.
HEM / O / PHILIARoot word meaning ‘blood’ / combining vowel / suffix meaning ‘love of’

Nonconstructed medical terms:If a medical term is not constructed from a combination of word parts, then it is called ‘nonconstructed’. These are words derived from other languages, words derived from names of people, from initials that form acronyms,
or from abbreviations. To learn the meanings of nonconstructed terms, you must simply commit them to
memory.
The term ‘pasteurize’ refers to the process of
heating milk to a temperature that kills
harmful microorganisms. The term is derived from
the name of its inventor… Louis Pasteur
(1822-1895).
