What is a Prefix?

A prefix consists of one or more letters placed at the beginning of a stem word. Prefixes provide an easy way to create new words. Adding prefixes to words recognized by the literate public makes the spelling and meanings of new words easier to understand. Once you understand common prefixes you can logically and consistently use them to create a variety of new words.

Prefix definition:

In English, a prefix is a letter/a group of letters attached to the beginning of a word to form a new word. In simple words, a prefix is a few letters put at the beginning of a word to change its meaning.

For instance, you can apply the prefix de- to negate the original word. The prefix de- means to undo something. When applied to the root word the new word’s meaning becomes opposite. For example, adding de- before value creates the word devalue. Value and devalue are terms with opposite meanings.

A prefix is a type of affix which is attached to the start of the root word. There are many different prefixes that are extremely common within the English language.
