100 Prefix Words List with Meanings and Examples

There are some letters that change the function of a word in a sentence when added with these words. They are either attached before the word or after it. The group of letters which come at the beginning of the word are called Prefixes. Each prefix, like a suffix, has its own meaning which completely changes the sense of the word. Prefixes make one root-word to be used in different meanings without a need to memorize a lot of vocabulary words. Prefix itself makes vocabulary rich and easy to be used in daily life. There are many prefixes being used, for example, dis-, mis-, anti-, non-, etc. Here is a long list of prefixes with examples one must remember.
