This is the way how the red wavy line disappears.
If you…
Click on "File" in the ribbon and select "Options".
In the next dialog box, open the Document Review section.
Check the box next to "Check spelling as you type".
Spelling errors are then marked with red wavy lines.
That is the explanation of what the underlined red wavy line stands for in word.

Two main colors are used in Word: The red wavy line, also known as a serpentine line, circles the words red, which are misspelled according to current spelling rules. In addition to typical spelling errors, words are underlined in red after the comma, as they correspond to the old spelling. Typos and reversed letters are also marked in this way.
If a word or entire parts of a sentence are underlined with a double blue line, there is a formatting or grammatical error. So anyone who builds a grammatically incorrect sentence construction or, for example, uses an enumeration in a sentence, but adds the singular to it, is kindly advised of this.
Even careless mistakes such as a space before punctuation, a missing after or double space, a common form of idiot spaces, do not go undetected by Word and are underlined in blue.
The text is from my research on the internet. But please keep in mind that my knowledge of Word as a simple user is very limited.
Thank you for your understanding and patience
