A superscript or subscript is a character such as a number or a letter. That is set slightly below or above the normal line of type, respectively. It is usually smaller than the rest of the text. Subscripts appear at or below the baseline, while subscripts are above. Subscripts and superscripts are perhaps most often used in formulas, mathematical expressions, and specifications of chemical compounds and isotopes, but have many other uses as well.
In professional typography, subscript and superscript characters are not simply ordinary characters reduced in size; to keep them visually consistent with the rest of the font, typeface designers make them slightly heavier (i.e. medium or bold typography) than a reduced-size character would be. The vertical distance that sub- or subscripted text is moved from the original baseline varies by typeface and by use.

Why would anyone need to use Subscript?
- As a reference marker, where a superscript number follows a statement, and the corresponding reference is in the footer.
- In mathematics, a superscript number is also used to represent an exponent.
- To show standard abbreviations, like the Copyright mark, trademark, and registered mark.
- Ordinal indicators, such as 1st, 2nd, 3rd, and 10th.
