Uppercase, also known as capital letters or all-caps, refers to text in which all letters are
in their uppercase form. It's commonly used for emphasis, headings, acronyms, and shouting in
written communication. Uppercase text tends to grab attention but can be harder to read in
long passages.
Lowercase refers to text in which all letters are in their lowercase form. It's the most basic
form of casing, often used for general text, URLs, filenames, and informal communication.
Lowercase text is typically easier to read and more casual in tone.
Sentence case refers to text in which the first letter of each sentence is capitalized, while
the rest of the letters are lowercase. It's widely used in formal writing, including articles,
books, and academic papers. Sentence case helps maintain readability and follows standard
grammatical conventions.
Title case is similar to sentence case but with additional rules for capitalization. In title
case, the first letter of each word (excluding certain minor words like articles,
conjunctions, and prepositions) is capitalized, while the rest of the letters are lowercase.
Title case is commonly used for titles of books, articles, headlines, and other published
works.
AP title case is a specific style of title case commonly used by news organizations, including
the Associated Press. It follows similar rules to standard title case but with some variations
in capitalization, such as capitalizing all verbs and pronouns regardless of their role in the
sentence. AP title case aims to provide consistency and clarity in news headlines and titles.
Superscript refers to a style of text formatting where characters are raised above the
baseline and reduced in size, typically used for footnotes, mathematical expressions, and
annotations. In superscript text, certain characters are replaced with their Unicode
counterparts, which are visually smaller and positioned higher than standard characters.
Superscript is commonly used in scientific and mathematical contexts to denote powers,
indices, and annotations.
