What Are Letter Casing Conventions?
Letter case determines the capitalization style of written characters. Different disciplines—from headline journalism and book publication to computer programming and database architecture—adhere to specialized capitalization rules.
Supported Formats Explained
- Sentence case: Capitalizes only the first letter of each sentence and leaves subsequent characters lowercase, matching standard prose grammar.
- lower case: Converts every single character to minuscule lowercase. Useful for sanitizing search tags and emails.
- UPPER CASE: Converts all alphabetic letters to majuscule capital letters. Standard for warning notices and acronyms.
- Title Case: Capitalizes the initial letter of every principal word while leaving minor articles and prepositions lowercase.
- camelCase: Concatenates words without spaces, capitalizing each word except the first. Heavily used in JavaScript variable names.
- snake_case: Replaces spaces with underscores (
_) in lowercase. Standard in Python, SQL, and database column names. - kebab-case: Replaces spaces with hyphens (
-). Standard in web URL slugs and CSS class definitions.
