Depending on the version of Word you have, if the first option doesn’t work, try CTRL and =. If you still don’t get it, then we explain the definitive method.
Access from Menu
Depending on your version of Word and your Windows or keyboard language, the key combinations may not work. In that case the most practical is to use the menu.
Write the word that contains the subscript in the standard way, and highlight the letter you want to subscript. In old versions of Word go to the Format menu , and go to Font. In modern ones, look for the Tool Ribbon, go to the Home, Format and Font tab.
Inside Font are the Subscript and Superscript icons. Press one or the other as you need:
Note: Please note that keyboard shortcuts do not work with online versions of Word.
Font Dialog Box
Write the word that contains the subscript in the standard way, and highlight the letter you want to subscript. Find the Font in Home Tab and click on the right below corner arrow symbol then click on the subscript box to apply.
First, find the part of the document where you want to insert subscripted special characters. Place the cursor and find the Insert button in the toolbar. Next, a drop-down menu will appear. Select Special Characters.
After selecting Special Characters, a pop-up image will appear on the screen. Use the search box in the upper left corner and enter Subscript. After you find the character that meets your needs, click the icon. The subscript character will be inserted at the cursor position.
