Outline Level

The Outline Level of a paragraph has nothing to do with outline numbering
The Outline level refers to the Heading level - ie the level at which the paragraph will appear in Outline view.
This is the property that you see in the Format > Paragraph dialog box under Outline Level.

All Built-in heading styles have an outline level.
Level 1 - for main heading - Heading 1
Level 2 - for a sub heading - Heading 2
This is the difference between Heading styles and all other styles
If you create your own heading styles they too will have outline levels.
A heading style is any style that has an Outline Level between 1 and 9.
If a style is not a heading style then is has an Outline Level of Body Text.
In the case of numbered headings ?? The outline level and list level of the paragraph

These are notes of reference, explanation or comment. A word in the main text can be marked with a footnote or endnote reference mark.
Footnotes appear on the same page as the text they explain. Endnotes reside at the end of each chapter (Insert > Footnote, Next)
