Formula & Technical Specifications
Title Case capitalizes the first character of each word. Sentence case capitalizes only the first letter following sentence delimiters. Programming casing formats strip non-alphanumeric characters and join word stems using camel humps, underscores, or hyphens.
Limitations, Edge Cases & Best Practices
Title case converts every word initial. For strict Chicago Manual of Style or AP style title casing (which lowercases short prepositions), manually verify minor articles if required.

Frequently Asked Questions
What is CONSTANT_CASE used for?
CONSTANT_CASE (e.g. MAX_BUFFER_SIZE) is the standard convention in programming languages like C, Java, JavaScript, and PHP for immutable configuration constants and environment variables.
Will punctuation in paragraphs be preserved in Sentence case?
Yes. Sentence case preserves standard commas, semicolons, and periods while properly capitalizing the initial word after each terminal period, exclamation mark, or question mark.
