A superscript or subscript is a number, figure, symbol, or indicator that is smaller than the normal line of type and is set slightly above it (superscript) or below it (subscript). When you add a trademark, copyright, or other symbol to your presentation, you might want the symbol to appear slightly above the rest of your text. If you’re creating a footnote, you might also want to do this with a number.
Apply superscript or subscript formatting to text
Select the text that you want to format as superscript or subscript.
On the Home tab, in the Font group, click Superscript or Subscript .
Insert a superscript symbol
For certain symbols that are almost always superscript, such as ® and ™, simply insert the symbol and it will automatically be formatted as superscript.
On the Insert tab, click Symbol.
Click or scroll to Letterlike Symbols, and click the symbol you want to insert.
