Etymology

thesis (n.)

late 14c., "unaccented syllable or note, a lowering of the voice in music," from Latin thesis "unaccented syllable in poetry," later (and more correctly) "stressed part of a metrical foot," from Greek thesis "a proposition," also "downbeat" (in music), originally "a setting down, a placing, an arranging; position, situation" (from reduplicated form of PIE root *dhe- "to set, put").

The sense in logic of "a formulation in advance of a proposition to be proved or debated" is attested by 1570s (contrasted to hypothesis ; in rhetoric it is opposed to antithesis ); that of "dissertation presented by a candidate for a university degree" is from 1650s. The uncertainty of the prosodic sense might have kept it from being established in English. Related: Thetic ; thetical ; thetically .

From Late Middle English thesis ( “ lowering of the voice ” ) [ 1 ] and also borrowed directly from its etymon Latin thesis ( “ proposition, thesis; lowering of the voice ” ) , from Ancient Greek θέσῐς ( thésis , “ arrangement, placement, setting; conclusion, position, thesis; lowering of the voice ” ) , from τῐ́θημῐ ( títhēmi , “ to place, put, set; to put down in writing; to consider as, regard ” ) [ 2 ] [ 3 ] (ultimately from Proto-Indo-European *dʰeh₁- ( “ to do; to place, put ” ) ) + -σῐς ( -sis , suffix forming abstract nouns or nouns of action, process, or result ) . The English word is a doublet of deed .

Sense 1.1 (“proposition or statement supported by arguments”) is adopted from antithesis . [ 2 ] Sense 1.4 (“initial stage of reasoning”) was first used by the German philosopher Johann Gottlieb Fichte (1762–1814), and later applied to the dialectical method of his countryman, the philosopher Georg Wilhelm Friedrich Hegel (1770–1831).

The plural form theses is borrowed from Latin thesēs , from Ancient Greek θέσεις ( théseis ) .

Prefixes and suffixes for research writing

Many words are made up of a root word and an affix . An affix is a word part that is attached to the beginning or the end of a root word; this affix then changes the meaning of the root word.

A prefix is a word part that is added to the beginning of a word to create a new meaning. For example, if the prefix “un” is added to the root word “happy”, we get a new word that has the opposite meaning to happy: “unhappy”.

A suffix is a word part that is added to the end of a word to create a new meaning. For example, if we take the root word “care”, we can change its meaning by adding the suffix “ful”, to give us the word “careful” (meaning “cautious” or “paying attention”). Alternatively, we could add the suffix “less” to “care”, to give us a word with a very different meaning: “careless” (meaning “not concerned” or “lacking in attention”).

Many words that we use in science use prefixes and suffixes that are derived from Greek or Latin. While this may seem complicated, once you become familiar with some of these prefixes and suffixes you will often be able to work out the meaning of scientific words, even if they are new to you.

Consider this example:

The word part “cyte” is derived from the Greek word for “cell”.

The word part “erythro” is derived from the Greek word for “red”.

The word “erythrocyte” means “red blood cell”.

The word “leucocyte” means “white blood cell” (the word part “leuco” being derived from the Greek word for “white”).

Note that some affixes can act as suffixes or as prefixes, depending on the word they are being used in.

For example, in the word “cytology”, meaning “the study of cells”, the word part “cyte” appears at the beginning of the word, rather than at the end as it does in “erythrocyte”. The word part “ology” comes from the Greek word that means “the study of”.

Look at the list of affixes below. Then, based on this list, answer the following questions.

  • Endo – within
  • Exo – outside
  • Iso – equal
  • Macro – large
  • Micro – small
  • Ology – the study of
  • Therm – temperature
  • What is the term for an animal’s skeleton that is inside its body?
  • What is the term for an animal’s skeleton that is outside its body?
  • What is the term for a process in which a system changes, for example, its pressure or volume, but the temperature remains the same?
  • If the word part “osteo” comes from the Greek word for “bone”, what is the scientific name for a “bone cell”?
  • What is the word part missing from the list of affixes that is needed to make a word that means the study of tiny living things?

Answers are below.

Definition of suffix  (Entry 2 of 2)

transitive verb

Did you know?

What are prefixes , suffixes , and combining forms ?

Prefixes and suffixes are both kinds of affixes . That is, they are word parts that attach to the beginning or end of a word or word base (a word stripped down to its simplest form) to produce a related word or an inflectional form of a word. Examples are in- in informal and both re- and -ing in reporting .

A third kind of affix is called an infix . Infixes are inserted into a word or word base. English uses very few infixes, but a couple examples are the plural-making s in words like cupsful and passersby , and various swear words, like damn in informal constructions like guaran-damn-tee .

A combining form is a form of a word that only appears as part of another word. There are a number of kinds of combining forms, each classified by what kind of word results when the form is used. For example, -wise in clockwise is an adverb combining form; -like in birdlike is an adjective combining form; -graph in photograph is a noun combining form; and -lyze in electrolyze is a verb combining form.

Combining forms are similar to affixes but can have a bit more lexical substance to them. Unlike affixes, combining forms are substantial enough to form a word simply by connecting to an affix, such as when the combining form cephal- joins with the suffix -ic to form cephalic . A combining form can also differ from an affix in its being derived from an independent word. For example, para- is a combining form in the word paratrooper because in that word it represents the word parachute . Para- is a prefix, however, in the words paranormal and paramedic . A combining form can also be distinguished historically from an affix by the fact that it is borrowed from another language in which it is descriptively a word or a combining form, such as the French mal giving English the mal- in malfunction .

“Two days after this adventure , the emperor, having ordered that part of his army which quarters in and about his metropolis, to be in readiness , took a fancy of diverting himself in a very singular manner. He desired I would stand like a Colossus, with my legs as far asunder as I conveniently could. He then commanded his general (who was an old experienced leader, and a great patron of mine) to draw up the troops in close order, and march them under me …”

Example #3: Heart of Darkness (by Joseph Conrad)

“We were on deck at the time, and the headman of my wood-cutters, lounging near by, turned upon him his heavy and glittering eyes…I assure you that never, never before, did this land, this river, this jungle, the very arch of this blazing sky, appear to me so hopeless and so dark, so impenetrable to human thought, so pitiless to human weakness . … he did not know exactly in what direction .”

Example #4: Macbeth (by William Shakespeare)

“And fixed his head upon our battlements . As whence the sun ‘gins his reflection Shipwracking storms and direful thunders break… As cannons overcharged with double cracks, So they doubly redoubled strokes upon the foe. Except they meant to bathe in reeking wounds .”

Example #5: Ode to Autumn (by John Keats)

“Season of mists and mellow fruitfulness , Close bosom-friend of the maturing sun… To bend with apples the moss’d cottage- trees , And fill all fruit with ripeness to the core; Thee sitting careless on a granary floor, Thy hair soft-lifted by the winnowing wind…”

Understanding Suffix (Examples, List of Suffixes, Grammar Rules, and More)

suffix

A suffix (in contrast to a prefix—although both are forms of affixes) are word parts that attach to the beginning or end of a word or base word (the simplest form of the word). They are used to produce a related word or an inflectional form of the word. For example, “reporting” and “porting.”

What is a suffix?

Suffixes are sequences of letters that are appended to the ends of words in order to modify and change their meanings.

By appending the suffix -ing to the verb ‘speak,’ for instance, we can get the present tense form ‘talking.’

Suffix definition

Suffix definition

A suffix is a series of letters that is added to the end of a root word and modifies or expands the meaning of the original word.

Suffixes can also be used in English to show if a word is a noun , verb, adjective , or adverb .

Difference between a prefix and a suffix

A prefix is a letter or group of letters that is attached to the beginning of a word. Having said that, it completely alters the definition of the word. On the other hand, the term “ suffix ” refers to a group of letters that is added to the end of a word.

As an illustration:

The prefix “im” affects the meaning of the word “patient” and appears in this context at the beginning of the word. Patient is synonymous with patience, while impatient conveys the opposite connotation of that word.

On the other hand, the word “painful” is formed by adding the suffix “ful” to the beginning of the word, which results in a new meaning. In addition, the meaning of the word shifts when a suffix is added. “Pain” is a noun, and “painful” is an adjective.

Nevertheless, prefixes and suffixes are both considered to be elements of affixes. The meaning of the base word, also known as the root word, can be altered by using one of these affixes.

A quick look reveals the following differences between a prefix and a suffix:

  • A root word’s prefix is any set of letters that appears before the root word itself. A suffix, on the other hand, is a collection of letters that are appended to the end of a basic word.
  • The prefix appears first in any word, and the suffix is always inserted at the very end.
  • A prefix can alter the meaning, and a suffix can likewise modify the meaning; besides , they can help format tenses .
  • In contrast, there is only one kind of prefix, but there are two kinds of suffixes: inflectional and derivational.

Suffix word examples

Why are suffixes used?

The best strategy to increase your vocabulary is to become familiar with various suffixes. Suffixes are typically added to the end of words to change or expand their meaning.

A suffix is an additional word that is added to the end of a root word in order to create new words. A root word is an autonomous word that may be used on its own.

Take, for example:

  • Play – Playing
  • Sing – Singing
  • Young – Youngest
  • Cute – Cutest
  • Big – Bigger
  • Tall – Taller

A word’s suffix can also indicate how it will be employed in a sentence . It can also indicate whether or not the word is a noun, verb, adverb, or adjective.

When appended to the end of a root word, certain suffixes allow for the spelling of the root word to remain unchanged.

What are the grammar rules that govern suffixes?

The English language places a strong emphasis on the use of suffixes .

They are put to use in the creation of new words as well as in the modification of the meanings of existing terms. There are two types of suffixes: vowel suffixes and consonant suffixes.

The following is a list of rules governing suffixes in grammar :

1. Double the amount of the consonant

When adding suffixes to some base words that end with a consonant, it is necessary to double the last letter. However, this requirement is only applicable in specific circumstances.

  • Fat – Fatter
  • Cool – Cooler
  • Hot – Hotter
  • Run – Running
  • Call – Calling
  • Write – Writing
  • Flip – Flipped
  • Clip – Clipped
  • Pamper – Pampered
  • Partner – Partnered
  • Fumble – Fumbling

2. Get rid of the silent E

The rule that dictates whether a word’s last silent “e” should be dropped or not depends on the letter that comes first in the suffix. This is true whether it’s a vowel or a consonant.

  • Give – Giving
  • Dine – Dining
  • Make – Making
  • Debate – Debatable
  • Excite – Exciting
  • Vote – Voting
  • Love – Lovable

3. Maintain the Final E

When adding a suffix to a word, there are a few instances in which the final “e” of the word remains intact.

  • Courage – Courageous
  • Advantage – Advantageous

4. Don’t forget the Y

When attaching a suffix, there are a few instances in which the letter “y” must be maintained at the end of the word.

  • Destroy – Destroyed
  • Bray – Brayed
  • Betray – Betrayal
  • Convey – Conveyed

5. Replace the Y in the phrase with an I

In order to add a suffix, it is sometimes necessary to alter the letter “y” that is found at the end of the word to the letter “i.”

  • Copy – Copied
  • Cry – Cried
  • Deny – Denied

6. Replace IE with Y

When you add the suffix -ing to a word that ends in “ie,” modify the ending of the word so that it ends in “y.”

  • Lie – Lying
  • Die – Dying

How to use a suffix

The addition of a suffix to the end of a word will alter what that word means when used in context.

The shift is not particularly obvious. A suffix will not transform a word into its antithesis or add another facet of meaning to it; rather, it will change the category that a word belongs to.

The suffix that means ‘origin is’ is ‘ish.’

For example:

  • Fool – Foolish

On a form (like a job application), the term “suffix” refers to the addendum that comes after a person’s last name. It provides further identification for someone in the same family with the same name.

A combining form is a word that only appears as part of another word. For example, “-wise” in clockwise. Combining forms are similar to affixes but have more lexical substance.

Inflectional suffixes don’t change the word class of the word after the inflection.

Derivational suffixes can get divided into two categories: class-changing derivation and class-maintaining derivation.

The word suffix is can be defined as adding a portion of a word to form a different word from its original meaning. The original meaning comes from New Latin Suffixium.

How to Write a Thesis Statement | 4 Steps & Examples

Published on January 11, 2019 by Shona McCombes . Revised on August 15, 2023 by Eoghan Ryan.

A thesis statement is a sentence that sums up the central point of your paper or essay . It usually comes near the end of your introduction .

Your thesis will look a bit different depending on the type of essay you’re writing. But the thesis statement should always clearly state the main idea you want to get across. Everything else in your essay should relate back to this idea.

You can write your thesis statement by following four simple steps:

  • Start with a question
  • Write your initial answer
  • Develop your answer
  • Refine your thesis statement

A thesis statement summarizes the central points of your essay. It is a signpost telling the reader what the essay will argue and why.

The best thesis statements are:

  • Concise: A good thesis statement is short and sweet—don’t use more words than necessary. State your point clearly and directly in one or two sentences.
  • Contentious: Your thesis shouldn’t be a simple statement of fact that everyone already knows. A good thesis statement is a claim that requires further evidence or analysis to back it up.
  • Coherent: Everything mentioned in your thesis statement must be supported and explained in the rest of your paper.

Prevent plagiarism. Run a free check.

The thesis statement generally appears at the end of your essay introduction or research paper introduction .

The spread of the internet has had a world-changing effect, not least on the world of education. The use of the internet in academic contexts and among young people more generally is hotly debated. For many who did not grow up with this technology, its effects seem alarming and potentially harmful. This concern, while understandable, is misguided. The negatives of internet use are outweighed by its many benefits for education: the internet facilitates easier access to information, exposure to different perspectives, and a flexible learning environment for both students and teachers.

You should come up with an initial thesis, sometimes called a working thesis , early in the writing process . As soon as you’ve decided on your essay topic , you need to work out what you want to say about it—a clear thesis will give your essay direction and structure.

You might already have a question in your assignment, but if not, try to come up with your own. What would you like to find out or decide about your topic?

For example, you might ask:

After some initial research, you can formulate a tentative answer to this question. At this stage it can be simple, and it should guide the research process and writing process .

Now you need to consider why this is your answer and how you will convince your reader to agree with you. As you read more about your topic and begin writing, your answer should get more detailed.

In your essay about the internet and education, the thesis states your position and sketches out the key arguments you’ll use to support it.

The negatives of internet use are outweighed by its many benefits for education because it facilitates easier access to information.

In your essay about braille, the thesis statement summarizes the key historical development that you’ll explain.

The invention of braille in the 19th century transformed the lives of blind people, allowing them to participate more actively in public life.

A strong thesis statement should tell the reader:

  • Why you hold this position
  • What they’ll learn from your essay
  • The key points of your argument or narrative

The final thesis statement doesn’t just state your position, but summarizes your overall argument or the entire topic you’re going to explain. To strengthen a weak thesis statement, it can help to consider the broader context of your topic.

These examples are more specific and show that you’ll explore your topic in depth.

Your thesis statement should match the goals of your essay, which vary depending on the type of essay you’re writing:

  • In an argumentative essay , your thesis statement should take a strong position. Your aim in the essay is to convince your reader of this thesis based on evidence and logical reasoning.
  • In an expository essay , you’ll aim to explain the facts of a topic or process. Your thesis statement doesn’t have to include a strong opinion in this case, but it should clearly state the central point you want to make, and mention the key elements you’ll explain.

A thesis statement is a sentence that sums up the central point of your paper or essay . Everything else you write should relate to this key idea.

The thesis statement is essential in any academic essay or research paper for two main reasons:

  • It gives your writing direction and focus.
  • It gives the reader a concise summary of your main point.

Without a clear thesis statement, an essay can end up rambling and unfocused, leaving your reader unsure of exactly what you want to say.
