Word roots, prefixes and suffixes:

 A root is a simple form of a word, or a part of a word, without any prefix or suffix. A prefix is a word fragment added in front of a word (e.g., bi-, pre-, un-). A suffix is a word fragment added at the end of a word (e.g., -hood, -less, -y). Combining roots with prefixes and suffixes produces new words. For example, prefix un- + root able = new word unable; root able + suffix -y = new word ably.

                Breaking a word down into root, prefix, and suffix might help you determine its literal meaning. Many English words were borrowed from Greek and Latin. It is a good idea to learn the meaning of common roots, prefixes and suffixes, as this could help you deduce the meaning of new and unfamiliar words.
