Problem 1: You don't have a spell checker.
If you don't use a spell checker, your texts probably have a few spelling mistakes. That doesn't matter, if you're sending an email to a friend or posting an update to Facebook. However, if you're writing for your work, you might come across as unprofessional. Therefore, this might be a good time to download a spell checker and to start using it.
Problem 2: You have a spell checker, but not in the language you're writing in.
If you're writing in multiple languages, you might stumble upon some problems with your spell checker.
- Your spell checker doesn't support the language you're writing in.
- You don't know how to switch it to the language you're writing in.
- All of your text is highlighted as errors.
- The auto-correct function of your spell checker changes some words to another language.
Language tool is a free spelling checker, which also indicates minor grammar mistakes. For example, it corrects the article of a noun in Dutch. It is so powerful that it finds mistakes that the spell checkers of commercial applications cannot find.
I prefer the standalone version of it, which I can use with any application via copy and paste. You can also overcome the second problem by switching off your built-in spell checker or using another text editor that doesn't have any built-in spell checker, like Notepad in Windows.
The standalone version is a java application, which doesn't require any installation (except if you don't have a java virtual machine installed, but that is also free and can be installed easily). It supports quite a few languages, including English, Dutch, German, French, Spanish, and Italian.
All you have to do is download and extract it. For convenience, you can place a shortcut on your desktop (via right mouse click on "languagetool-standalone.jar" -> Send to -> Desktop (create shortcut) in Windows).
Now, your spell checker is ready every time you want to send, post, or otherwise publish a text and you can't afford any spelling mistakes.
If you have any questions about this tool, please feel free to ask.
