You might come up with following questions:

What is proofing tools?
Why you need it?
Does it matter without it?

I am using MS Office 2016, writing a document in Khmer and got this alert.

In fact, simply, you can just download the package in your language and install it then you will get some special feature for the language you are using.

Proofing tools?

Proofing Tools are features that help the user create and edit documents. Document Proofing Tools include the following:

  • Spelling checker
  • Grammar/Style checker
  • Thesaurus
  • Translation Dictionaries
  • AutoCorrect List
  • Hyphenator
  • Contextual Speller

That’s a lot of good feature for your language to have from Microsoft office, you can have it for different MS Office version you have but if you doesn’t want those features, you do not need to install it.

To get to understand of each feature, please go to check here.
