“ Буквы должны быть добавочными (некорневыми) ” или “(Буквы должны быть добавочными (не корневыми)”? " Буквы должны быть добавочными (некорневыми) " или "(Буквы должны быть добавочными (не корневыми)"?
Both phrases are correct, but the first one is more common and easier to understand: "Буквы должны быть добавочными (некорневыми)". This means "Letters should be additional (non-root)". The second phrase just has an extra space before the word "корневыми", but it still conveys the same meaning: "(Letters should be additional (not root)".
