It is the middle of syllabus remediation week, and you have fixed headings, reviewed tables, added alt text, and then your accessibility checker flags something unexpected: “Document language not specified.”
You look at the warning and think, of course the document is in English. Anyone can see that.
The problem is that software cannot assume that unless the document explicitly tells it.
A document language tag is a setting in Microsoft Word that identifies the primary language of the document, such as English, Spanish, or French. It helps assistive technology, especially screen readers, interpret and pronounce text correctly. It is invisible to most faculty, but important for accessibility.
What Happens When a Language Tag Is Missing
Here is a common example. Your syllabus includes the sentence, "Students will submit a literature review by October 15." A sighted reader sees normal English and keeps moving. A screen reader, though, relies on the document language setting to know how to pronounce words using English pronunciation rules. If the document has no language tag, or the wrong one, pronunciation may be incorrect, and that can affect comprehension.
Before remediation, the text may be written in clear English while the file itself provides no structural clue about language. A screen reader may guess, apply the wrong pronunciation rules, or handle text inconsistently. After remediation, the content is exactly the same, but the document is tagged as English and interpreted correctly. That is a good example of what accessibility work often is: not rewriting the material, but making sure the file tells assistive technology what it needs to know.
A Real Example with Multilingual Content
This matters even more when a document contains more than one language. Imagine a syllabus that includes a reading like "Paulo Freire, Pedagogia del oprimido." If the whole document is tagged English, a screen reader may mispronounce the Spanish title. If that phrase is correctly marked as Spanish inside an English document, pronunciation can improve noticeably. That matters in language courses, international studies, and plenty of graduate syllabi that quote titles, names, or terms from other languages.
Why This Is a Compliance Issue
This may seem minor compared with missing headings or inaccessible tables, but it is part of digital accessibility standards.
Americans with Disabilities Act Title II applies to public universities. Many institutions also align with Section 508 and related accessibility expectations.
The United States Department of Justice has increased attention to digital accessibility enforcement since 2023. Institutional audits often check detectable structural issues, including missing language settings.
Because language tags are easy for software to test, they are commonly flagged.
That is why they appear in compliance notices.
How to Set a Document Language Tag in Word
The fix is usually quick. Open your syllabus in Word, select all text with Ctrl+A on Windows or Command+A on Mac, then go to the Review tab and choose Language, then Set Proofing Language. Select the correct primary language, which for many faculty will simply be English, and click OK. That applies a language setting to the document and gives assistive technology a much better starting point for pronunciation and interpretation.
If your syllabus contains passages in another language, mark those sections individually. Highlight the foreign-language text and set its language separately. For example, the primary document might be English while a quoted book title or key phrase is Spanish. That preserves meaning in a way that matters to actual users, especially in courses that regularly include multilingual content. After that, run Word's accessibility checker to confirm the warning is gone, and if you want a second pass, upload the file to AdaDocumentMaker to verify the language tag is present and check for any remaining compliance issues.
Common Faculty Mistakes
Mistake 1: Assuming spell check means language is set
Spell check and document language are related, but not identical. A document can appear to behave normally in Word while still lacking the accessibility metadata a screen reader needs. Passing spell check does not prove the language tag is correct.
Mistake 2: Ignoring copied content
Faculty often copy text from older syllabi, websites, or other documents. That content can carry inconsistent language settings into a file, which means a document may contain mixed tags without you realizing it.
Mistake 3: Leaving the wrong default language
Sometimes Word inherits a default language that is incorrect. The document may be tagged as another language accidentally, which can trigger accessibility warnings even when the text itself seems perfectly normal.
Why Students Benefit
Language settings support more than legal compliance. They help screen readers pronounce text more accurately, keep multilingual content understandable, make text-to-speech tools behave more predictably, and help reading-support technologies interpret the file correctly. A missing language tag can seem small, but it introduces little errors that accumulate across a document. The frustrating part is that the fix usually takes less than a minute once you know where the setting lives.
A Practical Workflow You Can Use Today
If you received a warning about document language, open the syllabus in Word, select all text, set the primary language correctly, and then mark any foreign-language phrases separately where appropriate. After that, run Word's accessibility checker and, if you want a second pass, upload the file to AdaDocumentMaker to confirm the issue is resolved. That addresses one of the most common structural problems faculty overlook because it is invisible until software points it out.
FAQ
What is a document language tag?
It is a setting in Microsoft Word that identifies the language of your document for assistive technology and other software.
Why does a screen reader need a language tag?
Screen readers use language settings to apply pronunciation and reading rules. Without that information, text may be interpreted incorrectly.
If my syllabus is obviously in English, do I still need this?
Yes. Human readers can infer the language. Software should not have to guess.
What if my syllabus contains more than one language?
Set the document’s main language, then tag sections in other languages separately where appropriate.
A Practical Place to Start
If your accessibility checker flagged missing document language or you are not sure whether copied content or multilingual text created language-tag problems in your syllabus, upload it to AdaDocumentMaker and get a free compliance report showing whether the document language is correctly set and what else may need attention before the semester starts.
