Wrong-language spelling suggestions in Gmail can come from Gmail, the browser, the operating system, or a writing extension. Identify the source before changing the account’s language. A translated interface and a spelling dictionary are not necessarily the same setting.
Find which tool is marking the word
Inspect the suggestion menu and any visible extension indicator. Compare a short non-sensitive example rather than uploading a private draft to another spelling service. If multiple tools are active, their corrections can overlap or disagree.
Gmail’s own spelling and grammar support is not available in every language. An unavailable suggestion does not necessarily mean the account language is wrong, and changing the interface cannot guarantee support for a particular writing language.
Review Gmail’s controls
On a computer, open Settings → See all settings → General and inspect the spelling, grammar, and autocorrect options. Gmail’s separate Language setting changes its interface. Input tools help type supported scripts; they should not be described as a universal grammar-dictionary selector.
Choose the settings you need and save changes where offered. Check a fresh non-sensitive example after the change rather than assuming an existing underline immediately identifies the active tool.
Check the browser or device checker
Chrome provides spell-check controls under Settings → Languages. The spelling provider can depend on the operating system, and mobile keyboards have their own controls. Use the relevant browser or device guidance for language selection and custom words.
Chrome distinguishes Basic and Enhanced spell check. Its guide says Enhanced sends entered text to Google for improved suggestions, while Basic does not send that text to Google for spell checking. Review that distinction before enabling Enhanced solely to solve a language mismatch.
Handle mixed-language text deliberately
Check names, technical terms, and quotations manually. A valid word in one language can still be inappropriate in another, and an automatic correction is not a factual review. If an extension supplies the unwanted suggestions, inspect its own language and permission settings. Avoid granting a new extension broad access to confidential mail simply because the default checker does not support the language you need.
