How are subtopics in an outline marked?

Subtopics in an outline are typically marked using a combination of numbers, letters, and indentation. Here's how it works:

Roman Numerals (I, II, III, etc.) - Used for main topics

Capital Letters (A, B, C, etc.) - Used for subtopics of main topics

Arabic Numbers (1, 2, 3, etc.) - Used for subtopics of subtopics (if needed)

Lowercase Letters (a, b, c, etc.) - Used for subtopics of subtopics of subtopics (rarely needed)

Example:

I. Main Topic

A. Subtopic 1

1. Subtopic 1a

a. Subtopic 1a1

2. Subtopic 1b

B. Subtopic 2

Key Points:

* Indentation: Each level of subtopic is indented further than the previous one to create a hierarchical structure.

* Consistency: Use the same system of numbering and lettering throughout your outline.

* Clarity: The outline should clearly show the relationships between topics and subtopics.

This structured format makes it easy to organize your ideas and ensure a logical flow within your writing.
