4. 4 Prefixes Prefixes are used to change meaning. Prefixes never change the part of speech. Most suffixes change the part of speech. Many prefixes give a word a meaning which is the negative of the original. Examples are dis, in, un. Other prefixes change meaning in different ways, for example: multi + ethnic = multiethnic (=made up of many different ethnic groups)
