I am new to the community and I have a question about the grammar check in TeXstudio. As we know, some words are not recognized by the grammar checker, e.g., binarization. I am not very comfortable when the red underlines keep popping up. Also, in this case, we might actually have misspelling problems.
My question is that if there is a way to ignore some specific words such that these underlines could disappear. Some people say I should find .ign file and add the words into the file. However, I could not find this file in the dictionaries.

.ignfile, it is in%appdata%/TeXstudio/dictionaries– Troy Apr 22 '18 at 06:46add to dictionarypart. Or maybe I am misunderstanding your question. – Troy Apr 23 '18 at 09:05binarization, and selectAdd to dictionaryin the context menu. https://imgur.com/a/R8INBNr – Troy Apr 25 '18 at 07:51.ignfile is simply because you haven't added any words for the dictionary to ignore yet. If the above suggestion fails (it shouldn't), just create your ownen_GB.ign(or whatever<language>.ign), open it in Notepad, type inbinarization, and save. Then restart TXS. – Troy Apr 25 '18 at 07:57
