What Are Prefix And Suffix?

A prefix is a letter or a group of letters placed before a word to modify the word’s original meaning. In the word ‘Prefix’, ‘pre’ stands for ‘before’. Hence it remains attached before a word to change its original meaning. For example, in the word ‘impatient’, ‘patient’ is the original word. The prefix is ‘im’. Together they form the word impatient, which means the opposite of patient. Hence, a prefix modifies a word to make it mean the complete opposite of what it originally stood for. A suffix is a letter, or a group of letters joined at the end of a word to modify the way that word fits in a sentence grammatically. For example, in the word ‘walked’, the suffix is ‘ed,’ which, when added to the main word walk, changes the verb’s tense from present indefinite to simple past tense.

New Word Creation With Prefix And Suffix

Through the use of prefixes and suffixes, a new word with a new meaning is created. Some prefixes are created from words we use very frequently in modern times. For example, electronic mail is converted to email where ‘e’ is the prefix, which modifies the main word ‘mail.’ The ‘e’ is a recently added prefix.

It is vital to understand what various prefixes mean since the prefix can help us understand the meanings of many words they may be used in. However, a prefix may have more than one meaning. Some words use only a particular meaning of the same prefix.

For example, the letters ‘im’ is a prefix that can mean two things- ‘not’ or ‘into’. The word ‘impersonal’ means something that is not personal. Hence, ‘im’ here means ‘not.’ In the word ‘import,’ the prefix ‘im’ stands for ‘into.’

A single word may contain one prefix and one suffix. For example, in the word ‘unwittingly’, ‘un’ is the prefix, witting is the main word, and ‘ly’ is the suffix.

Prefixes Originating From Latin

Like many words in English, many prefixes have originated from Latin. Like all other prefixes, it is essential to know the meaning of the prefix to understand the meaning of the word.

For example- the prefix ‘trans’ has originated from Latin, and it is very versatile. It can mean across, over, beyond, like in the word transcontinental. It is also used in chemistry to denote distance, like in the word transition. It is also used to denote the sex of a person when the assigned sex does not match the sex they identify with, like in the word transgender. 

Another prefix which has its roots in Latin is ‘sub’. It can also be used to mean different things in different words. It can be used to mean under, below, secondary, or subordinate, like in words subjugate, submerge, etc. It is also used in chemistry and sciences like in the word subtract.

Prefixes Originating From Greek

Apart from Latin, many prefixes have originated from Greek. The prefixes that originate from Greek are generally used in sciences. For example, the prefix ‘di’ comes from Greek, and it means the double of something or two. It is used in the naming of various compound words in chemistry, like disulfide, dioxide, etc.

Another Greek originated prefix may be cited as the prefix ‘hyper.’ It is used to describe something abundant or exaggerated. It is also used in sciences, like, hyperbole, hyperactive, etc.
