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-. Suffixes are attached to the end of a word root to add meaning such as condition, disease process, or procedure.
The second part of a binomial is often a person's name in the genitive case, ending -i (masculine) or -ae (feminine), such as Kaempfer's tody-tyrant, Hemitriccus kaempferi. The name may be converted into a Latinised form first, giving -ii and -iae instead. Words that are very similar to their English forms have been omitted.

Unlike derivational suffixes, English derivational prefixes typically do not change the lexical category of the base (and are so called class-maintaining prefixes). Thus, the word do, consisting of a single morpheme, is a verb, as is the word redo, which consists of the prefix re-and the base root do.
