A prefix comes before the stem of a word, and the addition of the prefix changes the word's meaning. Prefixes are also called preformatives because they change the form of words. A suffix is similar to a prefix, except it is put at the end of a word to change its meaning. In addition to English, the Russian, German and Japanese languages also use prefixes.
