How to Make Superscript in Citation With Word

Automatic Citation

2. Click the 'References' tab on the ribbon.
3. Click the 'Insert Footnote' button or the 'Insert Endnote' button, located in the Footnotes section on the ribbon. Word will insert an automatically numbered citation superscript in the text, and it will also add a corresponding superscript number at the bottom of the page, if you inserted a footnote, or at the end of the document, if you inserted an endnote.
