You might often create new words by attaching certain letters at the beginning of an already existing word. Such words are known as prefixes. A letter or a group of letters that you place at the beginning of a word is known as a prefix. Prefixes and suffixes together are named Affixes.
The addition of prefixes changes the meanings of words. For instance, the prefix un- means “not,” “remove,” or “opposite.” The addition of the prefix un-to the word “educated” gives the word “uneducated,” which refers to someone who is not educated.
Prefixes cannot be considered words in their own right and therefore they cannot stand on their own. If they exist as independent words they will surely be separated from the root word by a hyphen. The two most common prefixes in the English language are un- and re-. The prefix “re-” signifies “again” or “back,” as in the given words redo, rethink, reply, repack, etc.

- Different prefixes in English have the same meanings. The prefixes such as un-, in- and non- all have the same meaning which is “not” or “opposite of.” Similarly, the prefixes mis- and ir- signify something that is “wrong,” “wrongly,” or “incorrectly ” done.
- Keep in mind double letters are possible. An example would be, if you place the prefix im- to words that begin with the letter “m,” you get two “m”s as in “immediate.” This is true in the case of the prefix un-. When you add the prefix to words that begin with the letter “n,” as in “unnoticed.” Several other prefixes come under the same category.
- When you add a prefix to a word, the spelling of the base word never alters. For example, the prefix un- brought about no change in the spelling of the word “happy.” And, the prefix re- similarly does not alter the spelling of the word “live” in “relive.”
- Beware of “lookalikes”. They are words that look like they have prefixes but do not. For instance, take the word “uncle” un- in the word is not a prefix. Similarly, the re- in the words “reach” or “real” cannot be considered as prefixes.
- There are prefixes with the same meaning with only slightly different spelling variations, as in the following words: imperfect, insensitive, illiterate, etc. The reason for similar spelling is the rules of pronunciation.
