What are Prefixes?

We use prefixes to make a new work as these are the attachable letters. We fix them at the beginning of a word that meanings becomes different from the actual word. You can change the negativity, relation expressions, place, time, and manner by joining prefix with the original word. For example; Possible (base word) - Impossible (prefix) - opposite (meaning) | Payment - non-payment - opposite | War - pre-war - time | Terrestrial - extraterrestrial - place (outside of/ beyond) | Cook - overcook - manner (too much) | What are the most common prefixes? In English language, the most common prefixes that make words negative are in-, dis-, un-, etc. And another prefix that shows repetition is re- as if we add it to the word build, it becomes rebuild. It means to build something again. Many prefixes show position of an object or something. We use Sub that meaning are under or below and we can find it in the words subway and submarine. Don't change the base word's spelling while adding prefix to a word. The words disappear (dis- and appear), undo, and happy all relate this rule. If spelling results in double consonant, you will have to follow this rule. For example, the spellings like irredeemable, misspell, and cooperation. Use hyphen while joining a prefix to a proper noun as in pro-American. You will add the hyphen after fixing the prefix. The example of this is like Self-esteem, or ex-husband. The use of hyphens in writing will reduce the misreading, confusion, mispronunciations with other words. Hyphenate the words to evade confusion with the other word. For example, re-cover meaning is to cover again, and the meaning recover is to regain or repair. When you will apply the hyphen, the word will make sense.

How to Use Prefixes

Prefixes in English are used to modify the meaning and context of a word. For example, the words pre-judgment or post-judgment modify the meaning and context of the word judgment. Pre-judgment refers to events before the judgment in the court was announce. The word post-judgment refers to the events that followed the announcement of judgment. Prefixes are also used in physics, but then again, their meaning remains the same. In Physics, prefixes are assigned to units that modify the magnitude of those units. If we assign the prefix ‘milli’ to the unit grams, it will reduce the magnitude of grams by 1/1000. There are several other types of prefixes as well in English and physics that have the same purpose. There use simple; they are written at the start of each word to change the meaning of that word.

In the English language, it is crucial to develop a thorough understanding of what prefixes and suffixes are. They are added to the start and at the end of the word, respectively, and change its meaning. As discussed, prefixes are words that we add to the start of a word, making a new word altogether. Some examples where prefixes are involved include unhappy, dissatisfied, subheading, redo, and many others. If you look at the prefixes being used here, you will see that these words, when looked upon separately, do not mean anything. Un, Sub, Dis, and Re are words that hold no meaning of their own, but when added to a word, they change its meaning. The most common prefixes include un, re, in, il, en, em, non, over, mis, inter, fore, de, trans, super, semi, anti, mid, and under.
