Prefixes, the most frequently used elements in the formation of Greek and Latin words, consist of one or more syllables (prepositions or adverbs) placed before words or roots to show various kinds of relationships. They are never used independently, but when added before verbs, adjectives, or nouns, they modify the meaning. Many prefixes are added to other words with a hyphen, but medical dictionary publishers are opting to drop the hyphen on many of the more common prefixed medical words.

Most prefixes are a part of words in ordinary speech and do not refer specifically to medical or scientific terminology, but there are many that occur frequently in medical terminology, and studying them is an important step in learning medical terms and building a medical vocabulary.
