- not provided
- Scenario
- Writing or editing a document in the Thai language using Microsoft Word.
- Observed behavior
- The spelling and grammar proofing tool marks words incorrectly, fails to identify misspelled Thai words, or provides incorrect suggestions.

Install and Enable Thai Proofing Tools

Microsoft Word requires specific proofing tools to check spelling in different languages. If these tools are missing, Word will not flag spelling errors in Thai text.
Launch Microsoft Word, click on the 'File' tab in the top-left corner, and select 'Options' at the bottom of the menu.
In the Word Options dialog box, click on 'Language' in the left-hand pane.
Under the 'Office authoring languages and proofing' section, click on 'Add a Language'. Select 'Thai' from the dropdown list.
Check the box that says 'Get proofing tools' and click 'Add'. Restart Microsoft Word to apply the changes.

Verify Text Proofing Settings
Check if the Thai text has been manually excluded from spell check.
Try WPS Office for Seamless Document Editing

- 3. Open Your Documents: Launch WPS Writer and open your existing Word files to start editing immediately.

Frequently Asked Questions
Why does Word check Thai spelling but not grammar?
Microsoft Word's proofing capabilities vary depending on the language. For Thai, Word supports basic spelling checks but lacks full grammar checking support because determining the correct sentence structure can be highly complex.
How can I report incorrect Thai spelling suggestions in Word?
You can submit feedback directly to the Microsoft Word team. Go to the 'Help' tab on the ribbon, select 'Feedback', and describe the inaccurate spelling results you are experiencing.
Does the 'Do not check spelling or grammar' option affect Thai proofing?
Yes. If the 'Do not check spelling or grammar' option is accidentally checked in your language settings, Word will completely ignore all errors in the selected Thai text, even if the proofing tools are installed.
