Spell check is a tool that helps to ensure that written documents are free of spelling errors. It is designed to identify and highlight words that do not match the standard dictionary of the language being used. However, sometimes spell check may default to a language other than English, leaving people confused and frustrated.
The reason behind this issue may vary. Firstly, it may be due to the default language settings on the device or app being used. For example, if your computer, phone, or software has its language settings set to another language, then the spell check will work in that language.
Secondly, sometimes spell check can detect a language based on the text input, which may not necessarily be English. For instance, if someone is typing in a word or phrase in a language besides English, spell check will identify it as such and provide suggestions based on that language.
Lastly, it can also be attributed to a bug or glitch in the spell check software -- which can happen on occasion. In such a case, the best solution is to try and restart the application or device to see if it resets the spell check language settings.
In summary, spell check not being in English can be due to a variety of reasons, ranging from device or app language settings to language detection from text input to software glitches. Nevertheless, it is essential to verify the language settings and restart devices or software before assuming there is an issue.
