MORE ABOUT UPPER CASE LETTERS

What are 

uppercase letters?

Uppercase letters are capital letters—the bigger, taller versions of letters (like W), as opposed to the smaller versions, which are called lowercase letters (like w).

Uppercase means the same thing as capital. Uppercase letters can also be called capitals.

Some uppercase letters are just larger, taller versions of their lowercase counterparts (like uppercase W and lowercase w or uppercase C and lowercase c), but in many cases the two versions of the letter take different forms altogether, such as uppercase A and lowercase a or uppercase B and lowercase b.

To capitalize a word is to make its first letter an uppercase letter. For example, to capitalize the word polish (which is here spelled with a lowercase p), you would write it with an uppercase P, as Polish.

The state of being capitalized or uppercase (or the process of making a letter an uppercase letter) is called capitalization, as in Please check your paper for proper punctuation and capitalization.

In English, uppercase letters are used at the beginning of words for a few different reasons. It is considered a standard rule of English to use an uppercase letter to start proper nouns (which are nouns that refer to specific people, places, or things—meaning one’s that have specific names), such as Jess, Mexico, and Nintendo. Using an uppercase letter at the start of a word can change the way the reader interprets its meaning, as in the case of polish (a verb meaning to make something shinier) and Polish (an adjective describing someone from Poland) or apple (the fruit) and Apple (the company).

We also use an uppercase letter for the first letter of the first word in a sentence. Sometimes, we use an uppercase letter for the first letter of each word in a title, as in To All The Boys I’ve Loved Before. This is sometimes called title case.

Some acronyms and abbreviations are written using all uppercase letters, such as NASA and U.S. A word written entirely in uppercase letters (like WHAT) is said to be written in caps or all caps.

Example: A lot of people don’t bother using uppercase letters in text messages unless they want to emphasize something.

Where does 

uppercase letter come from?

The term uppercase letter has been used since at least the 1730s. The words uppercase and lowercase come from printing. The process of physically printing things with printing presses involved trays, called cases, that were divided into compartments for holding different kinds of type (blocks with letters on them). The upper case held capital letters and the lower case held what came to be known as lowercase letters.

It can be confusing to know whether or not to use an uppercase letter in certain situations, but a capitalization guide can help.

Lowercase and Uppercase Letters: Definition and Meaning

The 26 letters in the English alphabet can take two forms: uppercase and lowercase. Each form serves a different function. Most of the letters you see in writing are lowercase.

Definition of Lowercase Letters

Lowercase letters are smaller and sometimes take a slightly different form than their uppercase counterparts.

Notice the L that starts the word Lowercase in the previous sentence. It’s larger than the other letters and looks different than the l in the word letters.

Lowercase letters are used more often than uppercase letters. They follow the first letter of a sentence or the first letter of a proper noun.

Definition of Uppercase Letters

Uppercase letters, also called capital letters, are used to start sentences and as the initial letter of a proper noun.

Uppercase letters are larger than their lowercase counterparts. Though most uppercase letters look similar to their lowercase partners, others take slightly different forms.

When Should You Use Lowercase Letters?

It’s easier to explain the function of lowercase letters by saying what they don’t do. Lowercase letters do not start sentences and are not used as the initial letter of a proper noun.

They are used for all the remaining letters in sentences and following the first letter of proper nouns.

Most of the letters you write will be lowercase. A quick scan of this article shows that uppercase letters are used in specific circumstances and lowercase are used everywhere else!

In the first sentence of the paragraph above, Most of the letters you write will be lowercase., only the M in Most is an uppercase letter. All the others are lowercase.

Use Lowercase Letters with Common Nouns

Nouns are words that represent a person, place, thing, or idea. There are two types of nouns: common and proper.

Common nouns refer to a non-specific person, place, thing, or idea. They are generic terms. The chart below shows the common noun version of the proper nouns used above.

Proper noun (capitalize first letter) Common noun (lowercase letters)
Joanna person
London city
France country
Tuesday weekday
September month

Proper nouns refer to a specific person, place, thing, or idea. For example, the name of a particular person, city, country, day of the week, or month is a proper noun.

  • Joanna
  • London
  • France
  • Tuesday
  • September

The initial letter of a proper noun is an uppercase letter. The rest are lowercase.

Sentence Examples with Proper and Common Nouns

These sentences contain both proper and common nouns (in bold). The proper nouns are capitalized, the common nouns contain only lowercase letters.

  • After work, Sue met friends for dinner.
  • The ancient poet Homer wrote The Odyssey and The Iliad.
  • My favorite day of the week is Sunday, and my favorite month is July.

When Should You Use Uppercase Letters?

Most often, capital letters are used to start sentences and proper nouns, but those aren’t the only times.

This list explains other circumstances that require uppercase letters.

1. The first word of a quote that’s part of a complete sentence

When an embedded quote is also a complete sentence, the first word of that quote should be capitalized.

  • Mary said, “We should go to the beach.”

2. Titles of literary or artistic works

Capitalize the first, last, and all other words in a title except conjunctions, articles, and prepositions of fewer than four letters. This is called “Title Case.” (Some style guides have even more specific guidelines, so always check!)

  • To Kill a Mockingbird
  • The Hunger Games
  • The Fault in Our Stars

3. Professional titles preceding a person’s name

When a title such as “Dr.” or “President” precedes a specific person’s name, capitalize it.

  • We will now hear from Dr. Jones, our keynote speaker.
  • President Biden will give a speech later today.

Use lowercase letters if the title is used as a description or not followed by a specific name.

  • The keynote speaker is Martin Jones, a doctor.
  • I’m watching the president give a speech.

If you feel overwhelmed by the different rules of capitalization, remember that ProWritingAid is here to help!

It’s a thorough grammar checker (and more) that will detect errors in capitalization for you.

4. The pronoun “I”

You should always capitalize the pronoun “I.”

5. Acronyms and Initialisms

An acronym is a word formed by taking the first letter of each word of a compound term. Initialisms are similar abbreviations, except that the letters are pronounced individually rather than forming a new word.

  • PIN is an acronym for personal identification number and is pronounced as the word “pin”
  • FBI is an initialism for the Federal Bureau of Investigation and is pronounced as individual letters F-B-I

Some phrases are also abbreviated as initialisms:

  • “Talk to you later” is TTYL
  • “As soon as possible” is ASAP

Acronyms and initialisms should always appear in uppercase form.

6. When adding emphasis

Be careful with this use of uppercase letters!

When you put words or sentences in ALL CAPS, a practice often seen in texts or posts, you add emphasis to your words. Consider how that emphasis will be perceived.

ALL CAPS statements carry more aggression and intensity than lowercase words. That’s not always a bad thing.

For example, texting someone “HAPPY BIRTHDAY!” instead of “Happy birthday” is a way to convey excitement and show you really mean those good wishes.

Other times, ALL CAPS can sound accusatory, demeaning, or rude.

Remember that ALL CAPS in writing makes it seem as though the speaker is yelling. Keep that in mind before you press “send” on your uppercase text or post!

A Summary of Lowercase and Uppercase Letters

Lowercase letters are used for common nouns and for every letter after the initial letter of the first word of a sentence.

Uppercase letters are most often used at the start of sentences and as the first letter of proper nouns, though there are other times to use the capital letter form too.

CAPITAL LETTERS - what are they (large or small)? Example

Capital letters are uppercase letters that are larger than lowercase letters.

What are capital letters?

In Russian writing, letters differ in their graphic design: some are large, others are small or lower case. Large letters are often referred to as capital letters. As can be understood from this "speaking" name, they begin headings, that is, they indicate the beginning of

  • sentences
  • period
  • paragraphs
  • stanzas
  • someone else's speech, etc.

    - By everyone is born for some work, - objected E. Hemingway and added:
    - By everyone who walks the earth has his duties in life.

    In an old style heals me.
    E There is charm in ancient speech.
    About is not like your words
    and are more modern and sharper.

    Bella Akhmadulina

    Capital letters are a common name. In Russian, a special linguistic term is used - capital letters. Once upon a time, at the dawn of handwriting, they were really carefully written at the beginning of a line, and decorated in every possible way to distinguish them from other ordinary letters. Emphasizing the initial letter of the first word is the oldest writing technique that was used before the invention of printing. When typography appeared, the tradition of using capital letters at the beginning of a sentence and to highlight proper names survived.

    Let's consider in detail the cases in which uppercase or lowercase letters are used in modern Russian.

    The use of capital letters

    Capital letters are used not only in headings, at the beginning of sentences, but also to highlight certain words found anywhere in written speech. These special words include

    • proper names;
    • items.

    In Russian orthography, proper names must be written with a capital letter:

    1. names, patronymics, surnames, pseudonyms, nicknames of people, names of gods, mythical creatures, fairy-tale and literary heroes

    • Tanya, Vasilek, Andryushka;
    • Alexander Sergeyevich Pushkin;
    • Gaius Julius Caesar;
    • Vladimir Krasnoe Solnyshko;
    • O'Henry (William Sidney Porter)
    • Curly, Chernysh, Beetle, Top;
    • Zeus, Hera, Apollo;
    • Vasilisa the Beautiful, Cinderella, The Nutcracker.

    2. animal names

    • Tortilla turtle;
    • cat Marquis;
    • dog Oliver;

    3. geographical names, except for generic words (krai, region, district, city, settlement, village, river, lake, mountain, sea, bay, etc.)

    • Krasnodar Territory;
    • Saratov region;
    • City of Mosty;
    • Veliky Ustyug;
    • Sokol settlement;
    • Ponizovye village;
    • Volga river;
    • Lake Seliger;
    • Red Sea;
    • Everest.

    4. astronomical names

    • Cygnus constellation;
    • Solar Galaxy;
    • Alpha Centauri.

    The words "Earth", "Moon" and "Sun" as the names of celestial bodies are written with a capital letter and with a lowercase letter if they are used as common nouns. Compare:

    Recently, astronomers have difficulty distinguishing spots on the Sun.

    Rosehip stood with large flowers turned towards the sun, covered with many buds (K. G. Paustovsky).

    Note that in proper names all words , their components, are capitalized , except for nouns denoting generic concepts and service words, for example:

    • city of Rostov-on-Don;
    • Ludwig van Beethoven;
    • Vicomte de Bragelonne;
    • Vasco da Gamma.

    In this way, proper names differ from the names of organizations, institutions, industrial associations, architectural monuments, etc.

    In titles, capitalize only the first word , for example:

    • Socio-Political Research Foundation;
    • Research Institute of Road Engineering;
    • Main Department of Internal Affairs;
    • House of scientists;
    • Bronze Horseman.

    The name may contain more capital letters if it contains a proper name, for example:

    • Kristall Association;
    • Information Telegraph Agency of Russia;
    • Great Hall of the Moscow Conservatory;
    • Supreme Court of the Russian Federation.

    The capital letter is also used in pronouns you, you, your in documents, business letters when addressing one person politely.

    What do uppercase and lowercase letters mean

    What are lowercase and uppercase letters? The examples are not always clear, so let's start with definitions:

    Capital or lowercase letters are graphic characters used in writing that are larger than line boundaries. They are also called the big ones.

    A lowercase letters are graphic characters that do not exceed the size of a line in writing. They are also called small letters.

    The very name "capital letters" arose in Russian from the verb "prescribe". In ancient texts there were no capital letters, all words were written from lowercase. And only at the beginning of the chapters, the first letter, which was called the “letter letter”, was depicted more than all the others. It was written by hand. Therefore, now capital letters are also called uppercase.

    In Russian, every lowercase letter has a capital counterpart. Even "b", "y" and "b", although it is difficult to imagine where they can be used. However, not all experts support this opinion and prefer to consider that the Russian language has 33 lowercase and only 30 capital letters.

    Another feature of the Russian language is that the spelling of large and capital letters does not always coincide. So, for example, the letter is different:

    • capital " A " and lowercase " a ";
    • capital " B " and lowercase " b ";
    • capital " D " and lowercase " d ";
    • capital " E " and lowercase " e " and some others.

    Uppercase and lowercase letters in different languages ​​

    Capital letters are used in many languages ​​of the Indo-European family: Greek, Slavic, Germanic and Romance.

    What does the capital letter mean in these languages? It can mean the beginning of a new phrase, a proper name, a geographical name, and much more. Below we will analyze in detail in which cases a capital letter is written.

    However, not all language systems can observe the use of capital letters. Hebrew, Arabic, Indian, Thai and other languages ​​use only lowercase alphabetic characters.

    There were no capital letters in the Glagolitic alphabet, the first Russian written language. Capital letters firmly came into use only in the 18th century and all thanks to the great reformer Peter I. He not only brought reforms to Russia, but also introduced a civil typeface that contained both small and large letters.

    There are many words in Hebrew that are spelled the same but read differently and have different meanings. For example, the word "דוד" can sound like "dod" and mean "uncle" , as "dud" - "bak" and as "David" is a male name. How do the Israelis understand where is the meaning? Exceptional context.

    Uppercase and lowercase letters: spelling rules

    Let's see what rules to follow when using uppercase and lowercase letters in Russian. And to make it easier to remember, let's give examples of uppercase and lowercase letters in words.

    Capital letter at the beginning of a sentence

    The basic rule is: always write a capital letter at the beginning of a sentence.

    Example: It's easy to make a term paper. It is necessary to choose a topic, write the text and check for errors. Pay special attention to words with -Н- and -НН-, conjugation of verbs and spelling of particles "not" and "neither" with different parts of speech.

    By the way! For our readers there is now a 10% discount on any kind of work.

    It is customary to capitalize not only the first word in standard sentences, but also each new line in poetic works. This rule works even when the author didn't finish the sentence:

    Night, street, lamp, pharmacy,

    Meaningless and dim light.

    Live at least another quarter of a century -

    Everything will be like this. There is no exit.

    If you die, you start over again

    And everything will repeat as of old:

    Night, ice ripples of the channel,

    Pharmacy, street, lamp.

    Alexander Blok

    Capital letter in proper names

    Another rule that always works: capital letters are written in proper names. It remains to figure out what applies to them.

    Proper names are the names of objects or phenomena that are unique and stand out from the general mass of homogeneous concepts.

    Conversely, common names are names that apply to entire groups of similar objects. Such nouns always begin with lowercase letters.

    Earth with a capital letter is a planet, and with a small one - a common name

    Let's look at specific cases when a capital letter is written in proper names. And also remember the exceptions, without which it is impossible to imagine the Russian language:

    Rule Example Exception
    Surnames, first names and patronymics of people Lev Nikolayevich Tolstoy, Pushkin, Mashenka, Marina Ivanovna. If proper names are used as a common noun, they are written with a lower case: Pikapers are modern don Juans and womanizers.
    In pseudonyms, nicknames and nicknames Maxim Gorky, Bolbes and Experienced. If nicknames are used for a whole group of people: Why are balls dangerous for society?
    Animal names Dolly the sheep, Barbos the dog, Murka the cat. If the nickname is used as a common name for the group: In the morning, any watchdog barks just like that.
    In the names of fairy-tale characters Princess Nesmeyana Mermaid, Puss in Boots.
    In the names of gods Jesus, Allah, Mara, Poseidon, Osiris, Quetzalcoatl. The word itself "god" can be written both with a capital letter and with a lowercase letter. In church texts, they often write with a capital letter, but in popular literature - with a small letter.
    In religious names Church of the Holy Sepulcher, Holy Scripture, Koran, Mother of God, Wailing Wall.
    Place names Arctic Ocean, Kilimanjaro, New York, Serpukhovo.
    In the names of streets and avenues Alexander Nevsky Square, Tsvetochnaya Street, Raduzhny Lane.
    In the names of astronomical bodies and objects Planet Venus, satellite of Jupiter, Halley's comet, Milky Way galaxy. If this is not an astronomical object, but a homonym: planet Earth and native land.
    In the names of historical eras and events The Renaissance, the October Revolution, the War of the Scarlet and White Roses.
    In the names of holidays Walpurgis Night, Independence Day, Victory Day, First of May, but May 1st. If this is the date of the holiday, then it is written with a small one: The New Year is celebrated on December 31st.
    In the names of awards Title of Hero of Russia, Order of the Legion of Honor, but Order of the Red Star.
    In legal official company and brand names that are quoted Suzuki Auto Concern, Gorbunov's Bureau Creative Agency, Orlovsky Park Hotel. The name is not quoted if it is written in Latin letters: Hilton hotel, Pixies creative agency, BMW concern.
    In the names of organizations and institutions Federation Council, United Nations, European Union.
    In the names of unique titles and positions President of the Russian Federation, Prime Minister. All other positions are written with a small one: NATO Secretary General, EU Minister, Bishop of the Russian Orthodox Church.
    Abbreviated CIS, IAEA, UN, PE, MIA, USA. Some abbreviations are always written with a small letter: university, college, dot, bunker, bum, interim, spa.
    In the titles of scientific articles, literary titles and other works The novel "War and Peace", the fairy tale "The Scarlet Flower", the article "Why sleep should be a priority for every student".

    What are capital letters in street names? Examples may vary depending on the literary norm. So, in the names Chistye Prudy, Kuznetsky Most, Nikitsky Gates , only the first word was capitalized. Now the norm has changed and both words are capitalized: Chistye Prudy, Kuznetsky Most, Nikitsky Gates . If in doubt about spelling, refer to dictionaries.

    Capital letter in adjectives

    There are several cases in which adjectives are written with a capital letter, and they also need to be remembered:

    1. If the adjective expresses belonging to a specific person. For example, Misha's shirt, Vanka's stories.
    2. If the adjective refers to the memory of a famous person. For example, Pushkin Evenings, Spring Tolstoy Readings.

    If the expression has become a common noun, then it is written with a lowercase letter: Sisyphean labor, Turgenev young ladies, oatmeal porridge.

    Capital letter after colon

    What other words are capitalized? Those with which direct speech begins. In the text, this is formalized as follows:

    • the words of the author come first;
    • then put a colon;
    • in quotation marks write the words of direct speech.

    Example: Ivanov sighed and said to the teacher: “You shouldn’t want to expel me for absenteeism, but I can refund my record book and student card.”

    A special case: with what letter to write the appeal "YOU"

    In official documents, letters and business correspondence, the appeal "YOU" and its derivatives are often written with a capital letter. It is believed that this form shows maximum respect for the interlocutor.

    In letters to a respected person, it is appropriate to write "You"

    However, the rules of the Russian language do not impose strict norms. They recommend using "you" only if the author intentionally wants to emphasize his special relationship to a particular person.
