Prefix and Suffix Topic
Prefix and Suffix Topic
The English language contains an enormous and ever-growing number of words. Enhancing your
vocabulary by learning new words can seem overwhelming, but if you know the common prefixes
and suffixes of English, you will understand many more words.
Mastering common prefixes and suffixes is like learning a code. Once you crack the code, you can
not only spell words more correctly but also recognize and perhaps even define unfamiliar words.
Prefixes
A prefix is a word part added to the beginning of a word to create a new meaning. Study the
common prefixes in the table of “Common Prefixes”.
Suffixes
A suffix is a word part added to the end of a word to create a new meaning. Study
the suffix rules in the following boxes.
Rule 1
When adding the suffixes –ness and –ly to a word, the spelling of the word does not change.
Examples:
Exceptions to Rule 1
When the word ends in y, change the y to i before adding –ness and –ly.
Examples:
• ready + ly = readily
• happy + ness = happiness
Rule 2
When the suffix begins with a vowel, drop the silent e in the root word.
Examples:
Exceptions to Rule 2
When the word ends in ce or ge, keep the silent e if the suffix begins with a or o.
Examples:
• replace + able = replaceable
• courage + ous = courageous
Rule 3
When the suffix begins with a consonant, keep the silent e in the original word.
Examples:
Exceptions to Rule 3
Examples:
• true + ly = truly
• argue + ment = argument
Rule 4
When the word ends in a consonant plus y, change the y to i before any suffix not beginning with i.
Examples:
• sunny + er = sunnier
• hurry + ing = hurrying
Rule 5
When the suffix begins with a vowel, double the final consonant only if (1) the word has only one
syllable or is accented on the last syllable and (2) the word ends in a single vowel followed by a
single consonant.
Examples:
1. He cracked the Civils Service Examination, he was ___ (success) for the second time.
2. Ria is ___ (child), she was crying a minute ago and suddenly she started laughing.
3. They are ___ (practice), perhaps they will win the ___ (champion) trophy.
4. My brother’s ___ (aim) is to be a ____ (mathematics) when he grows up.
5. He is ___ (manners), he does not know how to behave with elders.
6. The current ___ (govern) did as promised, the roads of the old city are now ___ (broad).
7. A ___ (combine) of motivation and hard work can fulfil your dreams.
8. The doctors have advised her to be ___ (stress) only then she can overcome the __ (weak).
9. She ___ (behave) in the class because of which teachers ___ (agree) to let her sit in the
class.
10. College days are ___ (memory) days because here only we build ___ (relation) that are
never ___ (forget).
Vocabulary building
Adding affixes to existing words (the base or root) to form new words is common in academic
English. Prefixes are added to the front of the base (like dislike), whereas suffixes are added
to the end of the base (active activate). Prefixes usually do not change the class of the base
word, but suffixes usually do change the class of the word.
The most common prefixes used to form new verbs in academic English are: re-, dis-, over-, un-,
mis-, out-. The most common suffixes are: -ise, -en, -ate, -(i)fy. By far the most common affix in
academic English is -ise.
Verbs
Exercise
e.g. Suffix used to form verbs with the meaning "cause to be".
Suffix Example
-ise stabilise, characterise, symbolise, visualise, specialise
-ate differentiate, liquidate, pollinate, duplicate, fabricate
-fy classify, exemplify, simplify, justify
-en awaken, fasten, shorten, moisten
Exercise
Nouns
The most common prefixes used to form new nouns in academic English are: co- and sub-. The
most common suffixes are: -tion, -ity, -er, -ness, -ism, -ment, -ant, -ship, -age, -ery. By far the most
common noun affix in academic English is -tion.
Exercise
e.g. Suffix added to a verb (V), noun (N) or adjective (A) noun
Exercise
Adjectives
Many adjectives are formed from a base of a different class with a suffix (e.g. -less, -ous).
Adjectives can also be formed from other adjectives, especially by the negative prefixes (un-, in-
and non-).
The most common suffixes are -al, -ent, -ive, -ous, -ful, -less.
Suffix Example
-al central, political, national, optional, professional
-ent different, dependent, excellent
-ive attractive, effective, imaginative, repetitive
-ous continuous, dangerous, famous
-ful beautiful, peaceful, careful
-less endless, homeless, careless, thoughtless
-able drinkable, countable, avoidable,
Exercise
Prefix Examples
un- unfortunate, uncomfortable, unjust
im-/in-/ir-/il- immature, impatient, improbable, inconvenient, irreplaceable, illegal
non- non-fiction, non-political, non-neutral
dis- disloyal, dissimilar, dishonest
Exercise
Mixed
Word formation
Formal written English uses nouns more than verbs. For example, judgement rather
than judge, development rather than develop, admiration rather than admire.
This is reflected in our admiration for people who have made something of their lives, sometimes
against great odds, and in our somewhat disappointed judgment of those who merely drift through
life.
All airfields in the country would be nationalised, and the government would continue with
the development of new aircraft as recommended by the Brabazon Committee.
judgment of those
treatment of children
development of new aircraft
-tion is the most common suffix used in this way. For example: alteration, resignation.
However others are: -ity ability, similarity, complexity; -ness blindness, darkness, preparedness; -
ment development, encouragement; -ship friendship; -age mileage; -ery robbery, bribery; -
al arrival; -ance assistance, resemblance.

👉 Prefix Meaning
Prefix is a letter or a group of letters that appears at the beginning of a word and changes the
word’s original meaning.

Prefix is a letter or a group of letters that appears at the beginning of a word and
changes the word’s original meaning.
Suffix Meaning
Suffix is a letter or a group of letters that is usually added onto the end of words, to
change the way a word fits into a sentence grammatically.
Nouns, verbs, adjectives and adverbs all tend to use different suffixes, so this makes it a little easier
to remember! Collectively, prefixes and suffixes are known as ‘affixes’. 👉

expanded in use.
Examples:
• Befriend, bewitch, besiege, beguile, become, berate, bejewel, bewail, bedazzle etc.
Prefix an-
An- is another Old English prefix. It is used to shift words into a negative meaning. This means
that the words usually describe something without, lacking, or just simply means not.
Examples:
• Anoxia, anastral, anegoic, anethical, anhistorical, aniconic, anisomeric, anisotomic,
anotia, anuria, etc.
Prefixes are words that don’t mean anything on their own. They only serve to change the
meaning of the word they are attached to. Prefixes, because of that, are not really words.
Example:
• DIS-
DISbelief, DISpleasure, DISconnect
DIS, by itself, does not mean anything. When it’s combined with another word it changes the
meaning.
Some prefixed are words that have a meaning on their own, but they are short and can be attached
to other words.
The prefix for is very old, and it comes from Scandinavian languages. It was adopted by the
English language and has been used for ages. Usually, the prefix for is added to words when they
are supposed to describe something that ends up being worse than it started.
Many words that have the prefix for are old, and are not used very commonly today.
Examples:
• Forbear, forbuy, forcut, fordo, forswearer, forgather, forhang, forlet, forlive, forset,
forslow, forstop, fortear, fortread, forwarn, forwork, etc.
Other words are used in English regularly, and the prefix has been integrated into the word. In
some words an E has been added between the suffix and the rest of the word. In other modern
versions the prefix has remained the same
Examples:
Prefixes by themselves are not allowed in Scrabble. This means that just putting any prefix such
as post-, pre-, neo-, eb-, or others, is not allowed.
However, you can use words that are built with prefixes. Only complete words are allowed
in Scrabble. This means that you can use postmodernism, instead of just modernism.
Prefixes as grammatical elements are not complete words. They cannot be any type of word
except a prefix. Prefixes are used to change words and are always added to another type of
words.
The only case when prefixes are complete words is when two or more words are hyphenated
together. Some examples are jet-black, tar-runway, hot-blooded, and others. In this case, two
full words are connected with a hyphen.
Prefix and postfix are terms used in programming and coding. They are connected to operators
and operands. Each appears in a different situation, and achieves different results.
A prefix is an expression where the operator appears in the expression before the operands.
This is then called a prefix expression.
A postfix appears in an expression when the operator appears in the expression after the
operands. This is then called a postfix expression
Suffixes
A suffix is a letter or a group of letters that is usually attached to the end of a word to form a new
word, as well as alter the way it functions grammatically.
Depending on whether it is a noun, verb, adjective or adverb, a different suffix would be required.
For example, the verb read can be altered to become the noun reader by adding the suffix -er. The
same verb can also be turned into the adjective readable by adding the suffix –able.
It is just as important to understand the definitions of suffixes as prefixes, because they too help
us to deduce the meanings of any new words that we learn. I have listed some of the most common
suffixes below:
👉 Suffix Examples
NOUN SUFFIXES
-er, -or person or object that does a reader, creator, interpreter, inventor,
specified action collaborator, teacher
VERB SUFFIXES
ADJECTIVE
SUFFIXES
ADVERB
SUFFIXES
So as you can see, affixes can dramatically change the definitions of words. Knowing the various
prefixes and suffixes along with their meanings can really help you to understand how words are
used, and also how they should be spelled.
Although these groups of letters (affixes) are important and assist with forming words, they are
not words in their own right and cannot stand alone in a sentence.
If they are printed or written alone, then they should have a hyphen before or after them to
demonstrate that they are to be attached to other letters to form words (the way I have listed them
in the above tables).
Suffix -itis
The suffix –itis is commonly used in medicine. It describes a type of infection, condition,
inflammation, or some medical diagnoses.
Examples:
The suffix -pathy comes from Greek, and is commonly used in medicine. It means to suffer from
a disease, or have a condition.
Examples:
Examples:
The suffixes -tomy or -otomy are often used in biology and medicine. They refer to medical
conditions, diagnoses, procedures, or operations.
Examples:
Examples:
The suffix -lysis of common biology, various sciences, and academics in general. It refers
to decomposition, loosening, breaking down, separation, or decomposition.
Examples:
-Osis is a very common suffix in biology. -Osis means to be infected with something, or means
a condition, state, abnormal process, and disease.
Examples:
General surgical punctures are described with the suffix -centisis. This suffix is used to denote
that a specific part of the body has been surgically punctured. It can be used with almost any
body part.
Examples:
In order to describe pain through the use of a suffix you can use any medical suffix to present
the condition. There is no specific suffix that denotes a type of pain. Instead, you can use
a variety of suffixes to describe a specific type of condition, or pain in a specific area.
Suffix examples:
Names can have suffixes depending on the person’s academic honors, religious affiliation,
political title, or family status.
• Bachelor’s degree: John Doe, A.B, B.A., B.A., Hons, B.S., B.E., B.F.A., B.Tech., L.L.B,
B.Sc., etc.
• Master’s degree: John Doe, M.A., M.S., M.F.A., LL.M, M.L.A., M.B.A., M.Sc., M.Eng etc.

• Academic doctorate: John Doe, Ph.D., Ed.D., D.Phil., D.B.A., LL.D, Eng.D., etc.
Political and religious title examples:
GRAMMATICAL SUFFIXES:
Pertaining to -as, -al, -ar, -ary. -ic, -ical, -ous, and -ile
Suffix -ism

The suffix -al is commonly used to make adjectives out of nouns. It means kid of, pertaining
to, having a form or character of something.
Examples:
The suffix –ist is used for nouns. It means a person who performs a specific action, produces
something specific, plays a specific instrument, holds a specific value, has a specific doctrine,
and others.
Examples:
The suffix -able is commonly used for adjectives. I refers to someone or something that is capable
of something, susceptible of, fit for, tending or given to something.
Examples:
The suffix -ic is used to create adjectives out of other words. It originally comes from Greek and
Latin, and it means that something, or someone, has the characteristic of something else.

• Acidic, episodic, comedic, melodic, nomadic, periodic, idiotic, psychotic, patriotic, athletic,
poetic, magnetic, emphatic, kinetic, prosthetic, chaotic, narcotic, academic, economic, etc.
Suffix -ion
The suffix -ion is of Latin origin. It denotes and action or condition, and it is often used to form
nouns out of adjectives.
Examples:
The suffix –tion is used to form nouns. They mean an action of something, or the result of
something.
Examples:
The suffix -ed is very versatile. It can be used in three different ways: 1) to form the past tense
for weak verbs, 2) to form adjectives out of nouns or verbs to describe someone or something,
3) added to nouns or verbs in order to form compound adjectives that are hyphenated.
Examples:
• 1) Acted, danced, posted, lived, wanted, hated, played, tried, named, called, walked, talked,
used, created, etc.
• 2) bearded, colored, angered, triggered, used, rugged, incorporated, incarcerated, floored,
stoned, etc.
• 3) cone-shaped, green-tinted, loose-fitted, off-handed, amateur-produced, well-defined,

Suffix -ly
The suffix -ly is added to various words depending on the purpose. It can be added to adverbs
to form adjectives, or to nouns in order for them to mean something that is repeated in certain
intervals.
Examples:
The suffix -ness is very common and is used often. It is used on adjectives and principles, in
order to create abstract nouns that denote a quality or a state.
Examples:
The suffix -er is used in many different ways, and is a common suffix in English. It can be attached
to verbs in order to create an agent noun that describes a person doing a specific action. It can
also be used to create nouns that describe a person’s job, location or origin, or a special
characteristic.
Examples:
The suffix -ate is added often to nouns, adjective, and verbs. When it is added to nouns it denotes
a group of people, an office or institution, or administrative region. When it is added to verbs
it changes the verb to mean that something is caused to change. When added to adjectives it
means that something is showing or full of something.
Examples:
There are multiple suffixes that mean something pertains to something else. These are: -as, -
al, -ar, -ary. -ic, -ical, -ous, and -ile. Some words incorporate more than one suffix.
Examples:
Account numbers and card numbers are divided into sections. While the prefix denotes the
bank issuing the card, the body is the account numbers, and the suffix is the account type.
The suffix is important because it lets the bank know which type of account is being used, and
that way customers can’t access operations not approved for the type of account. The suffix is
made up of two to three numbers.
Different numbers describe a different type of account. There are various types of accounts,
and each has a unique number profile for a specific bank.
Examples:
• Cheque account – 00, Number 2 account – 02, Fixed account – 03, Savings account – 30,
Credit card account – 40, Thrift club account – 50, Term deposit account – 81
👉 Combining Forms
When you are learning the different types of prefixes, it is important to remember that not every
word containing these combinations is a prefix. Sometimes words have ‘combining forms’, which
look very similar to prefixes but work differently!
Let me explain….
As you know, a prefix is a letter or a group of letters that appears at the beginning of words, but it
can also be removed from the base word, and the word would still be a word without it, even if the
meaning changes.
For example, non- means ‘not’ or ‘without’, this is used in words such as ‘nonsense’. The word
‘sense‘ can be separated from the prefix and it would still be a word on its own, even if the meaning
is different.
Combining forms are similar to prefixes, and are sometimes known as ‘chameleon prefixes’,
because they act like them and appear at the beginning of words like them, BUT the combining
form is intrinsic to the word, meaning it is a part of the word and cannot be removed.
They are called ‘chameleons’, because they change their spelling and physical form to suit the
word they are attached to!
So, combining forms act as prefixes but are different, because the remaining letters cannot be
separated to form an independent word.
Here are some examples of prefixes that are also ‘combining forms’:

Learning Objectives
The English language contains an enormous and ever-growing number of words. Enhancing your
vocabulary by learning new words can seem overwhelming, but if you know the common prefixes
and suffixes of English, you will understand many more words.
Mastering common prefixes and suffixes is like learning a code. Once you crack the code, you can
not only spell words more correctly but also recognize and perhaps even define unfamiliar words.
Prefixes
A prefix is a word part added to the beginning of a word to create a new meaning. Study the
common prefixes in Table 4.2 “Common Prefixes”.
Tip
The main rule to remember when adding a prefix to a word is not to add letters or leave out any
letters. See Table 4.2 “Common Prefixes” for examples of this rule.
Table 4.2 Common Prefixes
Exercise
Add the correct prefix to the word to complete each sentence. Write the word on your own sheet
of paper.
Suffixes
A suffix is a word part added to the end of a word to create a new meaning. Study the suffix rules
in the following boxes.
Rule 1
When adding the suffixes –ness and –ly to a word, the spelling of the word does not change.
Examples:
Exceptions to Rule 1
When the word ends in y, change the y to i before adding –ness and –ly.
Examples:
• ready + ly = readily
• happy + ness = happiness
Rule 2
When the suffix begins with a vowel, drop the silent e in the root word.
Examples:
Exceptions to Rule 2
When the word ends in ce or ge, keep the silent e if the suffix begins with a or o.
Examples:
Rule 3
When the suffix begins with a consonant, keep the silent e in the original word.
Examples:
Exceptions to Rule 3
Examples:
• true + ly = truly
• argue + ment = argument
Rule 4
When the word ends in a consonant plus y, change the y to i before any suffix not beginning with i.
Examples:
• sunny + er = sunnier
• hurry + ing = hurrying
Rule 5
When the suffix begins with a vowel, double the final consonant only if (1) the word has only one
syllable or is accented on the last syllable and (2) the word ends in a single vowel followed by a
single consonant.
Examples:
On your own sheet of paper, write correctly the forms of the words with their suffixes.
1. refer + ed
2. refer + ence
3. mope + ing
4. approve + al
5. green + ness
6. benefit + ed
7. resubmit + ing
8. use + age
9. greedy + ly
10. excite + ment
