Word Formation: Prefixes and Suffixes

  • Prefixes

A prefix is defined as a letter or group of letters that we add to the beginning of a word to form new words. We usually use prefixes to guess the meaning of words.

Look at the words tie, retie and untie.  What do they have in common?

They all include the word tie. So the word tie is the root. Adding a prefix changes the meaning of the root.

Adding a prefix changes the meaning of the root.

Here is a list of prefixes and suffixes, along with their meanings and examples, that we use in word formation.

 

prefixes and suffixes

The prefixes in-, im-, il-, ir-,un-, dis- have the same meaning. They mean ‘opposite of’ or ‘not’. When we add these prefixes to a word, they give its opposite.

  • Tips: 

  • im– is used before a word beginning with ‘m’ or ‘p’ {e.g. Immature, impatient…}

    Adjectives beginning with c usually take the prefix in{e.g. incorrect…}

  • il– is used before a word beginning with ‘l’ {e.g. illiterate, illegal…}

  • ir– is used before a word beginning with ‘r’ {e.g. irregular, irrelevant…}

  • There are no rules for in– , un– and dis

  • We can also use the prefixes un– and dis– with verbs to form their opposites. (e.g. untie, unfasten, unpack, undo, unlock, undress, disagree, disappear, dislike, disqualify, disobey, disconnect etc.)

The list below shows more prefixes with their meanings along with examples.

  • Suffixes

Suffixes refer to the letters or syllables that we add to the end of a word to create new words.

Knowing the different suffixes can enable you to guess the meaning of new words and recognize whether the word is a verb, a noun, an adjective, an adverb, etc.

The suffix can change the spelling of the original word. For example, the -e ending of the verb createand the adjective wiseis omitted when the suffix is added.

  • Create → creation
  • wise→ wisdom

The suffix changes the spelling of the original word.

Here is a list of suffixes with meanings and examples.
