Root words, base words, and affixes practice Base words are always words that can stand alone in English and have meaning. For example, cycle is a full word in English, but it can also be added to, to make words like bicycle and cyclist. Cycle is the base word, or the simplest form of the word without any prefixes or suffixes added. There are two main types of affixes: prefixes and suffixes. A prefix is a group of letters added to the beginning of a word. A suffix is a group of letters added to the end of a word. Here are some examples of base words with prefixes and suffixes attached: Decide: decides, decided, deciding, decision, indecisive, indecision Love: loves, loved, loving, loveable, unloved, lovely Root words come from Latin or Greek words. They can't be used alone in English. For example, aud is a Latin root word that has to do with hearing. This is the root of common English words like auditorium. Yet aud doesn't mean anything on its own in English.
