Spelling mistakes in email messages are embarrassing and best avoided. Yahoo! Mail does not include a built-in spell checker but that doesn't mean you can't check the spelling another way.

Fortunately, most web browsers, such as Firefox and Chrome, have built-in spell checkers that do a pretty good job at checking for errors as you type. When an error is found, a squiggly line is shown below the problem word so that you can right-click it for word suggestions.

  4. There are plenty of language packs you can download for Firefox if you want to add a new dictionary to the browser.

Chrome and Opera

Safari: From the body portion of the Yahoo! Mail message, right-click the text area and make sure the Check Spelling While Typing option is enabled in the Spelling and Grammar menu. This can also be enabled through the Edit menu.

You can optionally check for grammar mistakes too if you enable the option called Check Grammar With Spelling.

Choose Show Spelling and Grammar from the same menu if you want to change the dictionary Safari uses for spell check or if you want to move through each word individually to see word suggestions one at a time.

  1. Right-click the text field in the body of the message to find the Spellcheck menu; make sure the Check the spelling of text fields option is enabled.
