In computing, a spell checker (or spell check) is an application program that flags words in a document that may not be spelled correctly. Spell checkers may be stand-alone capable of operating on a block of text, or as part of a larger application, such as a word processor, email client, electronic dictionary, or search engine.
Google Chrome has a built-in spell-checker to automatically check what you're typing into web forms and text fields. This feature is enabled by default. To adjust Spell checker settings, please do following steps:
You can right click the word in the text field, then select Add to dictionary.
Note: The current version of Chrome doesn't support for removing a word from the dictionary.
