‘P’ is for prefix

letter-pOne of the most useful add-ons to words to create new words is called the prefix. It is also helpful for anyone studying English to understand the common prefixes, which in turn broadens your understanding of the words. The term prefix itself includes the prefix pre which means roughly to go before. As you may already observe, the prefix affects the meaning of the base word, sometimes to the point of imposing the opposite meaning to the original. Thus, if you take the word prefix itself, you can discern the approximate meaning as to fix before (a word).

Here is a list of common prefixes used in English. I am choosing just a sample that you should be familiar with. Each line has the prefix, meaning and example.
