Writing an important email with spelling mistakes, grammatical errors or typing mistakes can create an unprofessional impression. Gmail includes built-in Grammar suggestions, Spelling suggestions and Autocorrect features that can help identify or automatically correct common writing mistakes while you compose an email.

If Gmail suddenly stops highlighting spelling mistakes, does not suggest grammar corrections, or no longer automatically fixes obvious typing errors, the first place to check is Gmail's General settings.

Google's current Gmail Help documentation confirms that users can individually turn Grammar suggestions, Spelling suggestions, and Autocorrect on or off from Gmail's General settings on a computer.

This guide explains what these features do, how to enable or disable them, how to manually check spelling, and what to troubleshoot when the settings appear correct but Gmail still does not detect mistakes.

1. What Are Grammar, Spelling and Autocorrect in Gmail?

Although these options are related, they perform different functions.

Grammar Suggestions

Grammar Suggestions analyzes your writing and may identify grammatical problems while you compose an email.

For example:

Incorrect:

She have completed the report.

Gmail may identify the grammatical problem and suggest:

Correct:

She has completed the report.

Grammar suggestions normally provide recommendations rather than simply changing every sentence automatically.

Spelling Suggestions

Spelling Suggestions identifies words that Gmail considers incorrectly spelled.

For example:

Incorrect:

Please send me the detials.

Gmail may identify detials as a spelling mistake and suggest:

details

You can then accept or ignore the suggestion.

Autocorrect

Autocorrect works somewhat differently.

Instead of only identifying a typing mistake, Gmail may automatically replace certain obvious misspellings with the corrected word while you type.

For example:

You type:

recieve

It may automatically become:

receive

Autocorrect is useful for fast typing, although some users prefer to disable it because automatic corrections can occasionally change a technical term, product name, person's name or abbreviation that was intentionally typed.

Google specifically lists Autocorrect as a separate setting that can be independently enabled or disabled.

2. How to Enable Grammar, Spelling and Autocorrect in Gmail

These instructions apply primarily to Gmail opened in a desktop web browser.

Step 1 – Open Gmail

Open Gmail on your computer and sign in to the required Google or Google Workspace account.

Step 2 – Open Gmail Settings

Look at the upper-right corner of Gmail.

Click the Settings gear icon.

The Quick Settings panel will open.

Step 3 – Click "See all settings"

At the top of the Quick Settings panel, click:

See all settings

Gmail will open its complete configuration page.

Step 4 – Open the General Tab

At the top of the Settings page, select:

General

Normally, Gmail opens the General tab automatically.

Google documents this same navigation path:

Gmail → Settings → See all settings → General.

Step 5 – Find the Grammar Section

Scroll down until you locate the setting related to:

Grammar

You should see options similar to:

Grammar suggestions on

and

Grammar suggestions off

Select:

Grammar suggestions on

if you want Gmail to identify possible grammar mistakes while composing messages.

3. How to Enable Spelling Suggestions

Continue down the same Settings → General page.

Locate:

Spelling

Select:

Spelling suggestions on

This enables Gmail's built-in spelling suggestions.

Google currently provides separate on/off controls for both Grammar and Spelling suggestions.

4. How to Enable Autocorrect

Immediately around the same section, locate:

Autocorrect

Choose:

Autocorrect on

Gmail can now automatically correct certain spelling mistakes while you type.

For most users, enabling all three options is a good starting configuration:

Grammar suggestions: ON

Spelling suggestions: ON

Autocorrect: ON

5. Save the Gmail Settings

After changing the options, scroll to the bottom of the General settings page.

Click:

Save Changes

If Gmail automatically applies the setting in your current interface, you may not always be required to perform a separate save operation, but when the Save Changes button is displayed, use it before leaving the page.

Return to your Inbox afterward.

6. Test Whether Gmail Spell Check Is Working

Do not assume that the setting is working immediately. Test it.

Click:

Compose

Type a sample message containing intentional mistakes, such as:

I recieved your mesage and I will definately send the document tommorow.

If spelling assistance is active, Gmail should identify at least some obvious misspellings or offer corrections depending on the active Gmail and browser writing tools.

Try another sentence containing a grammatical error:

He have completed the work.

If Grammar Suggestions is active and Gmail recognizes the issue, it may provide a correction.

7. How to Disable Grammar Suggestions in Gmail

Some users do not want Gmail analyzing grammar while writing.

To disable it:

1. Open Gmail.
2. Click Settings.
3. Click See all settings.
4. Select General.
5. Scroll to Grammar.
6. Select Grammar suggestions off.
7. Save the changes if required.

Google confirms that Grammar suggestions can be independently switched on or off.

8. How to Disable Spelling Suggestions

Follow:

Gmail → Settings → See all settings → General

Find:

Spelling

Select:

Spelling suggestions off

Save the changes if requested.

9. How to Disable Autocorrect

If Gmail keeps changing technical words, customer names, abbreviations or product names incorrectly, you may prefer to disable only Autocorrect while leaving spelling suggestions enabled.

Open:

Settings → See all settings → General

Find:

Autocorrect

Select:

Autocorrect off

This configuration can be particularly useful for IT professionals, programmers, accountants and other users who frequently type abbreviations, model numbers, commands, software names or specialized terminology.

10. Recommended Gmail Configuration

For normal business email users, a practical configuration is:

Feature	Recommended
Grammar Suggestions	ON
Spelling Suggestions	ON
Autocorrect	ON
Smart Compose	Optional
Smart Compose Personalization	Optional

If you regularly type technical terms or customer-specific abbreviations, consider:

Feature	Recommended
Grammar Suggestions	ON
Spelling Suggestions	ON
Autocorrect	OFF

This way Gmail can warn you about potential mistakes without automatically replacing text.

11. Grammar, Spelling and Autocorrect vs Smart Compose

These features should not be confused with Smart Compose.

Smart Compose attempts to predict words or phrases while you type and provides writing suggestions that can help complete sentences faster.

Google describes Smart Compose as a Gmail feature that offers suggestions as you enter text. It has separate Writing Suggestions and personalization controls in Gmail's General settings.

For example, you type:

Thank you for your...

Smart Compose might suggest:

response.

This is different from correcting a misspelled word.

Therefore:

Spelling Suggestions = identifies spelling mistakes.

Grammar Suggestions = identifies grammatical issues.

Autocorrect = automatically fixes certain typing mistakes.

Smart Compose = predicts what you may want to write next.

12. How to Enable Smart Compose

If you also want predictive writing assistance:

Open:

Gmail → Settings → See all settings → General

Scroll to:

Smart Compose

Select:

Writing suggestions on

Google's current instructions place Smart Compose under the General settings section.

You may also see:

Smart Compose personalization

with options such as:

Personalization on

or

Personalization off

Google states that personalization can use your writing style to customize suggestions.

13. Gmail Grammar and Spelling Are Enabled but Still Not Working

This is where troubleshooting becomes important.

Gmail writing assistance can overlap with your web browser's own spell-checking system and with third-party browser extensions.

If Gmail's settings appear correct but spelling or grammar checking still does not behave as expected, check the following.

14. Check Chrome Spell Check

If you use Google Chrome, Chrome itself also contains spelling functionality.

Therefore, text appearing inside Gmail may sometimes be affected by:

Gmail's writing tools

and/or

Chrome's spell checker

and/or

browser extensions

This is why disabling something in Gmail does not necessarily remove every spelling or grammar underline you see.

A Gmail Community troubleshooting response specifically notes that browser spell checking and extensions can continue producing writing suggestions independently of Gmail settings.

15. Check Chrome Language Settings

In Chrome, open:

Chrome → Settings → Languages

Look for spelling-related options.

Depending on the current Chrome version and configuration, you may see spell-check controls for supported languages.

Make sure the language you are actually typing in is enabled appropriately.

For example, if you primarily write emails in English but the browser is configured for another language, spelling detection can behave unexpectedly.

16. Basic vs Enhanced Spell Check in Chrome

Chrome may provide different spell-checking modes depending on version and configuration.

If Gmail appears to be providing unexpected corrections, also review Chrome's spelling configuration.

A Google Gmail Community troubleshooting answer recommends checking Chrome's spell-check setting because browser-level spelling assistance can affect Gmail independently of Gmail's own options.

17. Check Your Gmail Language

Language configuration can affect writing assistance.

Open:

Gmail → Settings → See all settings → General

Check:

Language

Ensure Gmail's display and typing environment correspond appropriately with the language you normally use.

Google also provides input-tool configuration under Gmail's language settings for supported environments.

18. Check Whether a Browser Extension Is Interfering

Extensions that modify text can interfere with Gmail's built-in writing tools.

Examples include:

• Grammar-checking extensions
• Spell-checking extensions
• Translation extensions
• AI writing assistants
• Text expansion utilities
• Clipboard utilities
• Security extensions that inspect webpage content

A common example is Grammarly or another writing assistant.

If two different proofreading systems operate simultaneously, you may see different colors of underlines, duplicate suggestions or corrections that continue even after Gmail's native settings are disabled.

Google's Gmail Community troubleshooting guidance recommends disabling grammar or writing extensions when diagnosing unexpected Gmail corrections.

19. Test Gmail in Chrome Incognito Mode

This is one of the best troubleshooting tests.

Open a Chrome Incognito window using:

Ctrl + Shift + N

Sign in to Gmail.

Compose a test email.

Check whether spelling and grammar behave normally.

Many Chrome extensions do not run in Incognito unless explicitly allowed.

Therefore:

Works correctly in Incognito but not normal Chrome

usually suggests that an extension, stored browser data or profile-specific configuration is contributing to the problem.

Testing Gmail in Incognito is also recommended in Google's Gmail Community troubleshooting guidance for writing-assistance issues.

20. Disable Extensions One by One

Open Chrome and enter:

chrome://extensions

Temporarily disable writing-related extensions.

Test Gmail after disabling each extension.

You do not necessarily need to permanently remove an extension.

The objective is to determine which component is producing or blocking the correction behavior.

21. Clear Gmail/Browser Cache if Necessary

If the settings were changed but Gmail continues behaving as though the old configuration is active, browser cache or stored site data may sometimes contribute to the issue.

Restart Chrome first.

If the problem remains, consider clearing relevant browser cache/site data and then sign back into Gmail.

Google Community troubleshooting guidance for Gmail writing-assistance issues also suggests clearing browser cache and cookies when simpler checks do not resolve the problem.

Be aware that clearing cookies may sign you out of websites.

22. Restart the Browser

After changing Gmail or browser language/spell-check settings:

1. Close all important browser tabs.
2. Exit Chrome completely.
3. Reopen Chrome.
4. Open Gmail.
5. Compose a test email.

This simple step can help ensure updated settings are being used.

23. Try Another Browser

If Gmail Spell Check works in one browser but not another, the problem is probably browser-related rather than an account-wide Gmail problem.

For example, test Gmail using:

• Google Chrome
• Microsoft Edge
• Firefox

If Gmail works correctly in another browser, focus troubleshooting on the original browser's language configuration, extensions, cache and profile.

24. Try Gmail Using Another Chrome Profile

Chrome profiles maintain separate:

• Extensions
• Cookies
• Preferences
• Language settings
• Browser configuration

If possible, create or use another Chrome profile and test Gmail there.

If Gmail works normally in the second profile, the issue is likely associated with the original browser profile.

25. Check Whether the Problem Affects Only One Google Account

Suppose you have:

Account A – spelling works

Account B – spelling does not work

while both accounts are tested in the same browser.

That strongly suggests reviewing the Gmail settings of Account B.

Remember that Gmail settings are associated with the account in which you changed them.

If you use several Google or Google Workspace accounts, verify that you are modifying the correct account.

26. Gmail Spell Check Works but Autocorrect Does Not

Do not confuse these functions.

You can have:

Spelling Suggestions: ON

and simultaneously:

Autocorrect: OFF

In that configuration Gmail may point out an incorrectly spelled word without automatically replacing it.

Therefore, check all three options separately.

27. Autocorrect Works but Grammar Suggestions Do Not

Similarly, Autocorrect being enabled does not necessarily mean Grammar Suggestions are enabled.

Return to:

Settings → See all settings → General

and verify:

Grammar suggestions on

Google exposes these writing-assistance options as separate controls.

28. Why Is Gmail Changing Correct Words?

Autocorrect cannot always know whether a term is intentionally written.

This can happen with:

• Person names
• Company names
• Brand names
• Software names
• Technical terminology
• Server names
• Domain names
• Product codes
• Abbreviations
• Accounting terminology
• Model numbers

If this becomes disruptive, a good configuration is:

Grammar Suggestions: ON

Spelling Suggestions: ON

Autocorrect: OFF

You will still receive warnings without allowing Gmail to automatically replace every recognized typo.

29. Why Are Words Still Underlined After Disabling Gmail Spell Check?

Because the underline may be generated by something other than Gmail.

Possible sources include:

• Chrome spell check
• Microsoft Edge spell check
• Firefox spell check
• Grammarly
• AI writing extensions
• Language extensions
• Operating-system typing assistance

A Gmail Community response specifically warns that grammar suggestions can originate from browser settings or extensions even when Gmail-related smart features have been switched off.

This distinction is extremely important when troubleshooting.

30. How to Identify Whether Gmail or the Browser Is Correcting the Text

A practical troubleshooting procedure is:

1. Disable Gmail's Grammar Suggestions.
2. Disable Gmail's Spelling Suggestions.
3. Disable Gmail Autocorrect.
4. Open a new Compose window.
5. Type intentionally incorrect words.
6. Check whether they are still underlined.
7. If yes, inspect browser spell-check settings.
8. Disable writing extensions temporarily.
9. Retest in Incognito.

If the underline remains after Gmail's writing assistance is disabled, it is likely being generated elsewhere.

31. Gmail Manual Spell Checking

Automatic suggestions are not your only option.

Gmail also provides writing-related assistance while composing messages, and Google documents spelling and writing settings as part of Gmail's email composition functionality.

Depending on the current Gmail interface, additional message options may provide access to spelling-related commands.

This can be useful before sending an important email.

32. Recommended Pre-Send Procedure for Important Business Emails

Before sending a quotation, proposal, legal communication, invoice-related message or other important business email:

1. Read the complete email once.
2. Review any spelling warnings.
3. Review grammar suggestions.
4. Verify customer and company names manually.
5. Verify email addresses.
6. Verify dates.
7. Verify monetary values.
8. Verify attachment names.
9. Confirm that the required attachments are actually attached.
10. Read the email once more before pressing Send.

Automated spelling correction is an assistance tool, not a substitute for final human review.

33. Important Difference Between Gmail Desktop and Mobile

The Gmail web interface on a computer exposes detailed Grammar, Spelling and Autocorrect settings as documented by Google.

On smartphones and tablets, typing correction can also depend significantly on the installed keyboard.

For example, Android users may use Gboard, which has its own suggestions and proofreading features. Google's Gboard documentation separately describes word suggestions, correction and proofreading functionality.

Therefore, if spelling works differently on your Android phone and desktop computer, that does not automatically indicate a Gmail problem.

The phone keyboard may be performing the correction.

34. Quick Configuration Summary

For Gmail on a computer:

Settings → See all settings → General

Then configure:

Grammar

Grammar suggestions on/off

Spelling

Spelling suggestions on/off

Autocorrect

Autocorrect on/off

Google confirms these three controls in the current Gmail Help instructions.

For predictive sentence completion, separately check:

Smart Compose

Writing suggestions on/off.

Then locate the Spelling, Grammar, and Autocorrect options.

2. How do I enable spelling suggestions in Gmail?

Go to:

Settings → See all settings → General → Spelling

Select:

Spelling suggestions on

and save changes if Gmail requests it.

3. How do I turn on grammar checking in Gmail?

Open:

Settings → See all settings → General

Find:

Grammar

Select:

Grammar suggestions on.

4. How do I enable Gmail Autocorrect?

Open:

Settings → See all settings → General → Autocorrect

Select:

5. Can I disable Autocorrect but keep spell checking enabled?

Yes. Gmail provides separate controls for Spelling Suggestions and Autocorrect, so you can keep spelling assistance enabled while turning automatic correction off.

6. Can I disable grammar checking without disabling spelling?

Yes. Grammar and Spelling Suggestions are separately configurable.

7. Why is Gmail Spell Check not working even though it is enabled?

Possible causes include browser language configuration, extensions, cached browser data, account-specific Gmail settings or another spell-checking system interfering with Gmail.

Testing in Incognito and temporarily disabling writing extensions are useful diagnostic steps recommended in Gmail Community troubleshooting guidance.

8. Why does Gmail still underline words after I disable its spelling suggestions?

The underline may be generated by your browser or a writing extension rather than Gmail itself. Browser-level spell checking and grammar extensions can operate independently of Gmail's settings.

9. Is Chrome spell check the same as Gmail spell check?

No. Chrome can perform browser-level spell checking, while Gmail has its own writing-assistance settings. This is why changing one setting may not necessarily disable the other.

10. Is Grammarly the same as Gmail Grammar Suggestions?

No. Grammarly is a separate third-party writing tool. If installed as a browser extension, it may continue checking Gmail text independently of Gmail's native Grammar Suggestions.

11. What is Smart Compose?

Smart Compose predicts text while you type and can suggest words or phrases to help complete an email faster. Google describes it separately from Gmail's spelling and grammar controls.

12. Is Smart Compose the same as Autocorrect?

No.

Smart Compose predicts what you may want to type next.

Autocorrect attempts to correct certain typing errors.

13. Can I turn off Smart Compose?

Yes.

Open:

Settings → See all settings → General → Smart Compose

and select:

Writing suggestions off.

14. Why does Gmail correct names or technical terms incorrectly?

Autocorrect may interpret an unfamiliar technical term, customer name, product name or abbreviation as a typing error.

If this happens frequently, consider disabling Autocorrect while leaving Spelling and Grammar Suggestions enabled.

15. Does Gmail automatically correct every spelling mistake?

No. Automated writing systems cannot identify every possible mistake, and the behavior can depend on language, context and available correction features.

Always manually review important emails before sending them.

16. Does Gmail Grammar work on Google Workspace accounts?

Gmail's Help documentation describes the Gmail writing settings generally. However, the exact features available to an account can also depend on the interface, account configuration and Google's current product rollout.

17. Can browser extensions interfere with Gmail spelling?

Yes. Writing, grammar and spelling extensions can independently analyze Gmail's compose box, so they can create additional underlines or suggestions. Google Community troubleshooting specifically recommends testing Gmail after disabling such extensions.

18. Why should I test Gmail in Incognito mode?

Incognito provides a useful comparison environment because many extensions are not active there by default. If Gmail behaves correctly in Incognito but not in your normal browser window, investigate extensions and browser-profile settings.

19. Can Gmail check multiple languages?

Language behavior depends on Gmail, browser and input settings. Gmail provides language and input-tool controls, while the browser or mobile keyboard may also have its own language-specific spelling configuration.

20. Why does spell checking work on my phone but not my computer?

Your phone keyboard may be performing spelling correction independently of Gmail. For example, Google's Gboard includes its own suggestion and proofreading capabilities.

21. Why does spell checking work on my computer but not my phone?

The mobile keyboard's spelling, language or text-correction settings may be disabled even though Gmail's desktop settings are configured correctly.

22. Can I leave Grammar and Spelling enabled but disable all automatic text changes?

Yes. A practical configuration is:

Grammar Suggestions – ON

Spelling Suggestions – ON

Autocorrect – OFF

You can then review suggestions without allowing Gmail's Autocorrect setting to replace recognized mistakes automatically.

23. Should business users enable Gmail Grammar and Spelling Suggestions?

For most users, yes. They can help identify common typing mistakes before messages are sent.

However, sensitive numbers, names, dates, contractual wording and technical information should always be verified manually.

24. What should I do if none of these solutions work?

Test systematically:

Another browser → Incognito mode → another Chrome profile → another Google account.

This helps determine whether the issue belongs to Gmail account settings, the browser, an extension or the local browser profile.

25. What is the best Gmail writing-assistance configuration for most users?

A useful general configuration is:

Grammar Suggestions: ON

Spelling Suggestions: ON

Autocorrect: ON

Smart Compose: ON or OFF according to preference

Users who regularly enter technical terminology may prefer to switch Autocorrect OFF while keeping Grammar and Spelling Suggestions enabled.

Conclusion

Gmail provides multiple writing-assistance features, and understanding the difference between them makes troubleshooting much easier.

The most important configuration path is:

Gmail → Settings → See all settings → General

From there, you can independently control:

Grammar Suggestions

Spelling Suggestions

Autocorrect

Google's current Help documentation confirms these controls and their location.

If the settings are enabled but Gmail still does not behave as expected, do not immediately assume Gmail itself is faulty. Check the browser's spelling settings, language configuration and installed writing extensions. Testing Gmail in Incognito or another browser can quickly help determine whether the problem is account-related or browser-related.

For important professional communication, Grammar Suggestions, Spelling Suggestions and Autocorrect can significantly reduce routine typing mistakes—but important names, financial amounts, dates, email addresses and technical information should still be reviewed manually before the message is sent.
