First, prefixes and suffixes, most of which are derived from ancient Greek or classical Latin, have a droppable vowel, usually -o-. As a general rule, this vowel almost always acts as a joint-stem to connect two consonantal roots (e.g. arthr- + -o- + -logy = arthrology ), but generally, the -o- is dropped when connecting to a vowel-stem (e.g ...
Meaning: a prefix used to make words with a sense opposite to that of the root word; in this case, meaning "without" or "-less". This is usually used to describe organisms without a certain characteristic, as well as organisms in which that characteristic may not be immediately obvious.
Interlingua's vocabulary is established using a group of control languages selected as they radiate words into, and absorb words from, a large number of other languages. A prototyping technique then selects the most recent common ancestor of each eligible Interlingua word or affix. The word or affix takes a contemporary form based on the ...
Prefixes do not normally require further modification to be added to a word root because the prefix normally ends in a vowel or vowel sound, although in some cases they may assimilate slightly and an in-may change to im-or syn-to sym-.

This is a list of terms and symbols used in scientific names for organisms, and in describing the names. For proper parts of the names themselves, see List of Latin and Greek words commonly used in systematic names. Note that many of the abbreviations are used with or without a stop.
This series of lists omits periods from acronyms and initialisms. It uses periods for certain abbreviations that traditionally often have them (mostly older Latin/Neo-Latin abbreviations). For example, both bid and b.i.d. may be found in the list. It generally uses the singular form of an abbreviation (not the plural) as the headword.
The English language uses many Greek and Latin roots, stems, and prefixes. These roots are listed alphabetically on three pages: Greek and Latin roots from A to G; Greek and Latin roots from H to O; Greek and Latin roots from P to Z. Some of those used in medicine and medical technology are listed in the List of medical roots, suffixes and ...
