Frequently Asked Questions
Is "and" capitalized in a title?
No. In major style guides (including APA, MLA, and Chicago Manual of Style), coordinating conjunctions such as "and", "but", "for", "nor", "or", "so", and "yet" remain lowercase unless they appear as the first or last word of the title or subtitle.
Do you capitalize "with" in a title?
In APA and MLA style, prepositions containing fewer than 4 or 5 letters (such as "with", "in", "on", "at", "to", "for", "by") are lowercase unless they start the title. Chicago style lowercases all prepositions regardless of length.
How do I change lowercase to uppercase in Microsoft Word?
Highlight the text in Microsoft Word and press Shift + F3 (or Fn + Shift + F3 on some laptops) to toggle between UPPERCASE, lowercase, and Title Case. You can also use the "Change Case" button (Aa) in the Home toolbar.
How do I make text all caps in Microsoft Excel?
In an adjacent empty cell, enter the formula =UPPER(A1) (replacing A1 with your target cell) and press Enter. For Title Case in Excel, use =PROPER(A1). Copy the formula results and paste as values.
What is the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter and capitalizes each subsequent word (e.g., myVariableName), while PascalCase capitalizes the very first letter as well (e.g., MyClassName).
When should I use snake_case vs kebab-case?
snake_case (with underscores) is standard for Python variables, database column names, and C programs. kebab-case (with hyphens) is standard for CSS class names, HTML attributes, and SEO URL slugs.
