By default, all uncommon words cause their definitions to appear at the bottom of the page as sorted footnotes.
Straight Latin text is always valid input.

Section Headings

For just a bold number, one after the preceding: 

@-@

For a bold number, one after the preceding, with arbitrary text: 

@-Arbitrary Text-@

For an arbitrary bold number: 

@-857-@

For an arbitrary bold number with arbitrary text:

Footnotes

For a numbered footnote below the definitions:

Arbitrary Definitions

To change the footnoted meaning of a word: 

casta @?fave?favus=honeycomb?faveo=to favor@ Lucina; tuus iam regnat Apollo.

To explicitly remove definitions of a word: 

tuus iam regnat @?Apollo@.

 

Enjoy! I'm open to lots more suggestions.
