Suffix definition
Suffixes are often used to change the word class of a word. For example, we can change the adjective 'excited' to the adverb 'excitedly' using the suffix -ly. We can also create comparative and superlative forms of the adjective by attaching the suffixes -er or -est to a root word eg. 'fast' to 'faster' and 'fastest'.
Suffixes can also change a word to show plurality, eg. 'dog' (singular) to 'dogs' (plural), and tense eg. 'play' (present tense) to 'played' (past tense), and more.
Examples of Suffixes
Happy → Happily
An example of a suffix is the word ending -ly in happily. The -ly in happily refers to the manner in which an action is performed (in a happy way); the adjective 'happy' becomes the adverb 'happily'.
Smart → Smarter/Smartest
Other examples are the suffixes -er in 'smarter' and -est in 'smartest'. The suffixes -er and -est allow us to compare two or more things. Adding the suffix -er to the word 'smart' would make the adjective comparative (smarter), and adding -est to 'smart' makes it a superlative (smartest).
Let's take a further look at how suffixes can change the grammatical properties, word class, or meaning of their root words. We will talk about the use of suffixes with nouns, adjectives, verbs, and adverbs.
Suffixes in Nouns
A noun is a word that names something or someone. This can be a name of a person, place, animal, food, concept, or thing eg. 'Joe', 'carrot', 'dog', 'London' etc.
Here are examples of suffixes in nouns. Notice how each example derives from a root word (eg. 'kindness' has the root word of 'kind'):
Suffix | Meaning | Examples |
-ist | One who practices something | dentist, optometrist, florist, chemist |
-acy | Quality, state of being | privacy, piracy, delicacy, legacy |
-ism | Theory, act, or belief | criticism, capitalism, classism, masochism |
-sion, -tion | Action or condition | decision, information, election |
-ship | Position held | internship, fellowship, citizenship, ownership |
-ness | State of being, condition, or quality | happiness, kindness, lightness, awareness |
-ity | Quality, state, or degree | responsibility, generosity, activity, captivity |
-dom | State of being or place | kingdom, freedom, boredom, wisdom |
-ment | Action, process, or result of | investment, judgment, establishment, retirement |
It's important to note that we do sometimes have to change the spelling of certain words in order to add the suffix; this often depends on the last letters of the word we want to change.
- eg. to change adjectives like 'responsible' and 'active' to the nouns 'responsibility' and 'activity' we need to remove the 'e' before adding the inflection 'ity'.
- eg. to change words like 'private' and 'pirate' to the nouns 'piracy' and 'privacy' we need to remove the letters 'te' before adding the inflection 'acy'.
Suffixes showing the plural
Here is an example of a suffix changing the grammatical properties of a noun:
- There was one balloon in the room.
Imagine another balloon is placed in the room. The noun ‘balloon’ must be altered in order to maintain the grammatical correctness of the sentence:
- There were two balloons in the room.
Here, the suffix -s is used to make the noun 'balloon' plural, 'balloons'. The suffix shows that there is more than one balloon.
Suffixes for agreement
The suffix -s isn't just used to show the plural. In Standard English, we have to add the suffix -s or -es to the base form of a regular verb when using the third person. For example, I wait → she waits or I watch → He watches.
Suffixes in Adjectives
An adjective is a word that describes a feature or quality of a noun, such as its colour, size, quantity etc.
Here are examples of suffixes in adjectives. Notice how each example derives from a root word (eg. 'beautiful' is from the root word 'beauty') :
Suffix | Meaning | Examples |
-ful | Full of | beautiful, deceitful, truthful, useful |
-able, -ible | Capable of being | notable, credible, preventable, sensible |
-al | Pertaining to | original, seasonal, emotional, theatrical |
-ary | Relating to or condition of | honorary, cautionary, necessary, ordinary |
-ious, -ous | Possessing the quality of | studious, nervous, cautious, humorous |
-less | Without something | useless, restless, hopeless, fearless |
-ive | Quality of or nature of | creative, destructive, receptive, divisive |
-worthy | Deserving of | trustworthy, noteworthy, newsworthy, praiseworthy |
Let's look at an example of the suffix -less changing the grammatical properties of the word 'fear'.
- The girl has no fear → The girl is fearless.
Here the suffix -less changes the noun 'fear' to the adjective 'fearless'. The suffix -less, therefore, shows that someone is without something.
Suffixes in Verbs
A verb is a word that expresses an action, event, feeling, or state of being.
Here are examples of suffixes in verbs. Notice how each example derives from its root word (eg. 'strengthen' comes from the root word 'strength') :
Suffix | Meaning | Examples |
-en | To become | strengthen, fasten, loosen, tighten |
-ed | Past action | cried, played, jumped, crafted |
-ing | Current or ongoing action | singing, dancing, laughing, cooking |
-ise, (-ize as the American spelling) | To cause or become | criticise, merchandise, villainise, socialise |
-ate | To become or be full of | reciprocate, regulate, passionate, considerate |
-ify, -fy | To cause or become | terrify, justify, satisfy, rectify |
Suffixes showing tense
Suffixes can change the grammatical properties of a verb by indicating when an action was performed. Take a look at the following example:
The man laughs at the pantomime.
The suffix -ed can be added to the root verb ‘laugh’ to indicate that the action occurred in the past:
The man laughed at the pantomime.
We can also add the suffix -ing to the verb 'laugh' to show a continuous action:
The man is laughing at the pantomime.
Suffixes in Adverbs
An adverb is a word that gives more detail about a word (often an adjective, verb, or another adverb).
Here are examples of suffixes in adverbs. Notice how each example derives from its root word (eg. 'excitedly' has the root word of 'excited') :
Suffix | Meaning | Examples |
-ly | Manner in which something occurs | excitedly, hurriedly, nervously, sadly |
-wise | In relation to | otherwise, clockwise, lengthwise, likewise |
-ward | Direction | forward, backward |
-ways | Direction | sideways, frontways |
Let's look at an example:
- The woman shouted in an excited manner → The woman shouted excitedly.
Here, the suffix -ly changes the word 'excited' from an adjective to an adverb ('excitedly'). This helps to express the meaning of the sentence in a more concise way.
Derivational or Inflectional Suffixes
There are two types of suffixes in English - derivational suffixes and inflectional suffixes. Let's look at what they are along with some examples.
Inflectional Suffixes
Inflection is a process of changing the grammatical properties of a word. Inflectional suffixes are therefore suffixes that change the grammatical properties of words.
For example, when we add the suffix -ed to the root word ‘laugh’, the present tense ‘laugh’ becomes the past tense ‘laughed’.
What distinguishes inflectional suffixes from derivational suffixes is that adding an inflectional suffix to the root word does not change the syntactic category (or word class) of the word. In other words, if a word is a verb and has an inflectional suffix added to it, it cannot change word class eg. if we add the inflectional suffix -ing to the verb 'sleep', this can't then be made into an adverb ('sleepingly') as it won't make sense. In other words, we can only add one inflectional suffix at a time.
Below are examples of inflectional suffixes belonging to different syntactic categories:
NOUNS:
Inflectional Suffix | Meaning | Example |
-s | Plural number | flowers, shoes, rings, cars |
-en | Plural number | children, oxen, chicken |
VERBS:
Inflectional Suffix | Meaning | Example |
-ed | Past action | wasted, screamed, jumped, removed |
-t | Past action | dreamt, slept, wept, crept |
-ing | Present action | sleeping, eating, laughing, crying |
-en | Past action | eaten, awoken, stolen, taken |
ADJECTIVES/ADVERBS:
Inflectional Suffix | Meaning | Example |
-er | Comparative | faster, stronger, longer, harder |
-est | Superlative | fastest, strongest, longest, hardest |
As you can see, inflectional morphemes maintain the word class of a word. 'Flower' and 'flowers' both remain as nouns whilst 'jump' and 'jumped' remain as verbs.
Derivational Suffixes
Derivational Suffixes create new words that ‘derive’ from the original root word.
Adding a derivational suffix to the root word often changes the syntactic category (or word class) of the word. For example, we can add the suffix -ation to the verb ‘derive’ to make it a noun ('derivation'). We can then add another suffix, -al, to make this word an adjective ('derivational')! These are examples of class-changing suffixes.
However, this is not always the case. The suffix -ist often maintains the root word’s syntactic category eg. 'classist' is a noun that is derivative of the noun 'class'. Another noun, 'pianist', is derivative of the noun 'piano'. The suffix -ist is an example of a class-maintaining suffix.
Here are some examples of both class-changing suffixes and class-maintaining suffixes:
Class Changing suffixes:
Suffix | Example | Word Class |
-ful | beautiful, bountiful | NOUN → ADJECTIVE |
-ise/ize | realise, visualise | NOUN → VERB |
-tion | situation, justification | VERB → NOUN |
-ment | judgement, punishment | VERB → NOUN |
-ly | stunningly, terrifyingly | ADJECTIVE→ ADVERB |
Class Maintaining suffixes:
Suffix | Example | Word Class |
-ism | classism, racism | NOUN → NOUN |
-ist | chemist, florist | NOUN → NOUN |
-ess | heiress, seamstress | NOUN → NOUN |
-ology | Ideology, methodology | NOUN → NOUN |
The Importance of suffixes in English
Let's look at the place of suffixes in English and why they are so important.
Suffixes as morphemes
Suffixes and prefixes are types of affixes.
An affix is a type of morpheme, which is the smallest unit of meaning.
More specifically, it is a bound morpheme, a type of morpheme that has to be part of a larger expression. They attach (or 'bind') to a root word.
Affixes are not words themselves, they must be attached to a root word to be used.
What are the benefits of using suffixes?
Expands our vocabulary, helping to improve our overall language use.
Helps to make a sentence more concise.
Trains learners to construct/deconstruct words and alter a word’s grammar or syntactic category eg. learning to convert nouns to verbs, nouns to adjectives, adjectives to adverbs, etc., helps us to understand sentence construction.
Can reveal a lot of extra information about a word, such as tense, word class, plurality, the meaning of the word as a whole, etc.
Suffixes are a big part of English grammar and an understanding of suffixes is essential for more varied language use.
Suffix - Key takeaways
A suffix is a type of affix that is placed at the end of a root word to change its meaning or grammatical function.
Suffixes are often used to change the word class of a word, show plurality, show tense, and more.
There are two types of suffixes in the English language - derivational suffixes and inflectional suffixes.
Inflectional suffixes change the grammatical properties of words.
Derivational Suffixes create new words that ‘derive’ from the original root word. Adding a derivational suffix to the root word can change the syntactic category of the word (class-changing suffixes) or maintain the root word’s syntactic category (class-maintaining suffixes).
A suffix is a bound morpheme meaning it must be attached to a root word.
