How to remove a language from Chrome?

This helped me:

1. Delete Chrome from your PC.
2. Disable location determination in Windows.
3. Install Chrome again.
4. Before you sync your account, check if the language is correct now.
5. If yes, then before you sync your account, disable "setting sync" in Chrome  (setting → Sync and Google services → manage sync → "disable settings").

This worked for me (copied from here).

The Chromium devs provided this workaround:

1. Open chrome://settings
2. Open JS console with Ctrl+Shift+J
3. Type chrome.languageSettingsPrivate.disableLanguage('hi')

where 'hi' is the 2 char language code (for example Hindi in this example).
