English Prefixes and Suffixes Rules

English Prefixes and Suffixes Rules

The English language contains an enormous and ever-growing number of words. Learning new words can be challenging and even tougher, but if you know the common prefixes and suffixes of English, you will understand many more words.

In other words, understanding how words are formed using prefixes and suffixes besides practicing them can make you able to spell words more correctly and also recognize and perhaps even define unfamiliar words. 

Prefixes and suffixes are collectively known as ‘affixes’. Some words have both a prefix and a suffix: 

prefix + root word + suffix 

un-accept-able


Prefixes

A prefix is a word part added to the beginning of a word to create a new meaning. The main rule to remember when adding a prefix to a word is not to add letters or leave out any letters. 

Here is some common prefixes for examples of this rule. See a wide list of common prefixes.

Prefix
Meaning
Example
dis
not, opposite of
dis + satisfied = dissatisfied
mis
wrongly
mis + spell = misspell
un
not
un + acceptable = unacceptable
re
again
re + election = reelection
super
above
super + script = superscript


Here are some common prefixes for metric measures.

millisecond
kilo-
one thousand times a unit

Using hyphen (-) with prefixes

Generally no hyphen is used when a prefix is added to a word. However, to avoid confusion in some situations and make the meaning of the word clearer, a hyphen can be used.

One example is where the prefix ends with the same letter that the word starts with. 

for example: co- and owner. Adding co- without a hyphen could change the pronunciation of the word and make the meaning difficult to understand. For this reason co-owner is clearer than coowner.

Confusion can also occur where the word has two meanings. 

for example: a remark is a spoken comment, but re-mark means to mark/assess an exam again. Using a hyphen in this situation can avoid confusion.

A hyphen is often used with a prefix before a proper noun, for example: un-American and anti-British. 

Finally, the prefixes ex-, self- and co- are often used with a hyphen.


Suffixes

A suffix is a linguistic element (a word part or a group of letters) placed at the end of a word to make a new word form, either inflected or derived. Suffixes are attached to a word for semantic (derivational) and/or grammatical (inflectional) reasons:

➤ inflectional (grammatical): for example, changing singular to plural (bag → bags), or changing present tense to past tense (talk → talked). In this case, the basic meaning of the word does not change.

➤ derivational (the new word has a new meaning, "derived" from the original word): for example, dance → dancer or fruit → fruitful


Inflectional suffixes

Inflectional suffixes do not change the meaning of the original word. So in "Every day I walk to school" and "Yesterday I walked to school", the words walk and walked have the same basic meaning. In "I bought one pen" and "I bought two pens", the basic meaning of the words pen and pens is exactly the same. In these cases, the suffix is added simply for grammatical purpose.


Derivational suffixes

With derivational suffixes, the new word has a new meaning, and is usually a different part of speech. But the new meaning is related to the old meaning - it is "derived" from the old meaning.

We can add more than one suffix, as in this example: 

         navigate (verb) + ation → navigation (noun) + al → navigational (adjective)

Suffixes enable root words to form different classes of words. 

        for example: -ion creates nouns / -ive creates adjectives / -ly creates adverbs. 

These classes of words (nouns, verbs, adjectives) have their own common suffixes.

Some common suffixes and their meanings. See a wide list of common suffixes.


Suffix
Meaning
Example
able
can be done
accept + able = acceptable
est
most
tall + est = tallest
er
more
fast + er = faster
er
one who
teach + er = teacher
dom
place or state of being
free + dom = freedom

Here are some suffixes rules to put in practice in you daily use of English:

Rule 1

When adding the suffixes -ness and -ly to a word, the spelling of the word does not change.

Examples: 

   • sad + ness = sadness

   • week + ly = weekly

Exceptions to Rule 1

When the word ends in y, change the y to i before adding -ness and -ly.

Examples: 

  •  easy + ly = easily

  • dingy + ness = dinginess


Rule 2

When the suffix begins with a vowel, drop the silent e in the root word.

Examples: 

  • share + ing = sharing

  • love + able = lovable

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: 

  • peace + able = peaceable

  • advantage + ous = advantageous


Rule 3

When the suffix begins with a consonant, keep the silent e in the original word.

Examples: 

  • peace + ful = peaceful

  • tire + less = tireless

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: 

early + er = earlier

embody + ing = embodying


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: 

run + ing = tanning (one syllable word)

forget + ing = forgetting (The accent is on the last syllable; the word ends in a single vowel followed by a single consonant.)

cancel + ed = canceled (The accent is not on the last syllable.)

refer + ed = referred


There are some differences in spelling between British and American English to consider. 

Examples:

American English
British English
analyze
analyse
traveled/traveling
travelled/travelling
defense
defence
civilization
civilisation
center
centre
humor
humour
dialog
