Uppercase letter definition: Uppercase letters are letters that represent the beginning of a sentence or a proper noun.

What are Lowercase Letters?

In writing, most letters are lowercase. Lowercase letters are all letters that do not begin a sentence or refer to a proper noun.

English alphabet lowercase letters: a b c d e f g h i j k l m n o p q r s t u v w x y z.

Examples of Lowercase Letters:

What are Uppercase Letters?

Uppercase letters are also known as capital letters. Uppercase letters signal to the reader that something is important or significant.

English alphabet uppercase letters: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z.

Examples of Uppercase Letters:

• Jones
  • This is a proper name, so the first letter of the title and the last name are capitalized

• Main Street
  • This is a proper noun so the first letter of each word is capitalized

When to Use Uppercase Letters

In English, the first letter of every sentence is capitalized. The uppercase letter signals to the reader that a new sentence is beginning.

Other uses of uppercase letters are detailed below.

All titles are considered proper nouns and require capitalization.

Examples:

• NATO
  • North Atlantic Treaty Organization
• UNICEF
  • United Nations International Children’s Emergency Fund
• SCUBA
  • Self-contained underwater breathing apparatus

• I would like to tour the Eiffel Tower.
  • Incorrect: I would like to tour the eiffel tower.
• Their names are Jake and Suzy.
  • Incorrect: Their names are jake and suzy.

When to Use Lowercase Letters

Use lowercase letters for all letters other than the first in a sentence, provided that there is no required use for uppercase letters in the sentence.

Examples:

• Every word in this sentence other than the first word is written in lowercase.
• The only words in this sentence that require uppercase letters are the proper nouns, London and Paris.

All nouns that are not proper nouns are called common nouns. All common nouns use lowercase letters (unless a common noun begins a sentence).

Examples:

• tree
• dog
• bird
• water
• air
• star
• street
• girl
• baby

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.

These are the lowercase forms of each of the 26 letters in the English alphabet.

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.

These are the uppercase or capital forms of the 26 letters in the English alphabet.

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 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.

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.

Uppercase and Lowercase Letters / Sudo Null IT News

I've gathered here some not-so-obvious facts about uppercase and lowercase letters that a programmer may encounter at work. Many of you have translated strings into “all uppercase” (uppercase), “all lowercase” (lowercase), “first capital, and the rest lowercase” (titlecase). Even more popular is the case-insensitive comparison operation. On a global scale, such operations can be quite non-trivial. The post is structured as a "collection of misconceptions" with counterexamples.

1. If I convert the string to uppercase or lowercase, the number of Unicode characters does not change.

No. The text may contain lowercase ligatures, which do not correspond to one character in upper case. For example, when translating to uppercase: fi (U+FB00) -> FI (U+0046, U+0049)

2. Ligatures are a perversion, no one uses them. If they are not taken into account, then I'm right.

No. Some letters with diacritics do not have an exact match in other case, so you have to use a combined character. Let's say the Afrikaans language has the letter ʼn (U+0149). In upper case, it corresponds to a combination of two characters: (U+02BC, U+004E). If you come across a transliteration of Arabic text, you may encounter (U+1E96), which also does not have a single-character match in upper case, so you will have to replace it with (U+0048, U+0331). The Wakhi language has a letter (U+01F0) with a similar problem. You may argue that this is exotic, but there are 23,000 articles in Afrikaans on Wikipedia.

3.

No. There is, for example, the letter "escet" ß (U+00DF) in German. When converted to uppercase, it turns into two SS characters (U+0053, U+0053).

4. Okay, okay, got it. We will assume that the number of Unicode characters can increase, but not more than twice.

No. There are specific Greek letters, for example, (U+0390) that turn into three Unicode characters (U+0399, U+0308, U+0301)

5. Let's talk about titlecase. Everything is simple here: I took the first character from the word, translated it into uppercase, took all the subsequent ones, translated it into lowercase.

No. Let's remember the same ligatures. If a word in lowercase begins with fl (U+FB02), then in uppercase the ligature becomes FL (U+0046, U+004C), but in titlecase it becomes Fl (U+0046, U+006C). The same with ß, but, theoretically, words cannot begin with it.

6. Those ligatures again! Well, we take the first character from the word, translate it into uppercase, if more than one character is obtained, then we leave the first one, and the rest back into lowercase. Then it will definitely work.

Won't work. There is, for example, the digraph dz (U+01F3), which can be used in text in Polish, Slovak, Macedonian or Hungarian. In uppercase it corresponds to the digraph DZ (U+01F1), and in titlecase it corresponds to the digraph Dz (U+01F2). There are other digraphs. The Greek language, on the other hand, will delight you with jokes with hypogegrammen and progegrammen (fortunately, this is rarely found in modern texts). In general, the uppercase and titlecase variants for a character can be different, and there are separate entries for them in the Unicode standard.

7. Good, but at least the result of converting a character's case to uppercase or lowercase does not depend on its position in the word.

No. For example, the Greek capital sigma Σ (U+03A3) becomes a lowercase ς (U+03C2) at the end of a word and σ (U+03C3) in the middle.

8. Oh, okay, let's process the Greek sigma separately. But in any case, the same character in the same position in the text is converted in the same way.

No. For example, in most Latin languages, the lower case for I (U+0049) is i (U+0069), but not in Turkish and Azeri. There, the lower case for I is ı (U+0131) and the capital case for i is İ (U+0130). In Turkey, because of this, enchanting bugs are sometimes observed in a variety of software. And if you come across a text in Lithuanian with accents, then, for example, a capital Ì (U + 00CC), which will turn not into ì (U + 00EC), but into (U + 0069, U + 0307, ​​U + 0300) . In general, the result of the conversion also depends on the language. Most of the complex cases are described here.

9. What a horror! Well, let's now correctly convert to uppercase and lowercase.

There are also many pitfalls that follow from the above. For example, it will not work with the German straße and STRASSE (the former will not change, the latter will turn into strasse). There will also be problems with many of the other letters described above.

10. M-yes… Maybe then everything is in the uppercase?

And it won't always work (although much more often). But, say, if you come across the notation STRAE (yes, there is a big escet in German and Unicode too), it will not match straße. For comparisons, letters are converted according to a special Unicode table - CaseFolding, according to which both ß and SS will turn into ss.

11. A-ah-ah, this is some kind of kapets!

Here I agree.

If some symbols are not displayed for someone, write me a private message, I will replace it with a picture.

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 lowercase. 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
• of the period
• paragraphs
• stanzas
• of someone else's speech, etc.

  - By everyone is born for some work, - E. Hemingway objected 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.

  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 was preserved.

  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 that are located anywhere in the written language. These special words include

  • proper names;
  • items.

  In Russian orthography, proper names are always 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 Red Sun;
  • 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.
