the introduction. Since more than 75% of medical terms are derived from Latin and Greek,
a discussion of the transcription to English of Greek and Latin terms is usually presented.
Most sections on etymology include comments on prefixes, suffixes, combining forms, and
compounds used in medical terminology. Often the Greek and Latin alphabets are
included in the etymology section of the introduction.
Plurals. A presentation on plural forms is included because many plurals are
irregularly formed and because many words have alternate plurals. This portion of the
introduction will indicate how plurals are presented and listed in the dictionary.
