This mean you can have a dictionary with project related terms and abbreviations which you use only when you are working on that project.

Spell and Grammar checking settings apply to a document range, so you can select all of the document and set the desired options. This will not affect other documents.

> check and correct the wrong spelling for only one word file.

do you mean to make sure spelling check against specific language(s)? or what's your ultimate goal behind this requirement?

Thank you for your reply. For example, if i type some words wrong, the Word will underline the wrong words with red line, but in some certain Word file, I need to type many words that the Word cannot recognize. In this way, Word will give a lot underlined red line, it is a mess in the file. If I do not want to close the function for all Word file, I just want to close the function for some certain Word file.

You can also select the text in the file with Ctrl-A and turn off the spelling checking for the selection.

You might be able to create a style with no spelling correction
