Instructions
Identify any prefixes. Prefixes appear at the beginning of a word and are usually two- to four-letter formations like "re," "pre" and "post," but they can be shorter or longer in some cases. If you are unsure of a suspected prefix, look it up in the dictionary and see if it is listed as a prefix.
Identify any suffixes. This step works exactly like Step 1, but rather than identifying prefixes at the beginning of the word, you identify any suffixes that might be at the end of the word. Common suffixes are "ly," "ing" and "er." If you are unsure of a suspected suffix, look it up in the dictionary and see if it is listed as a suffix.
Rewrite the word without prefixes and suffixes. The result should be the word root you are looking for.
Research the root word to identify its language of origin and meaning if you want to further your understanding of the original word's proper use.
