"More unviewable" is spelled as /mɔr ʌnˈvjuəbl/. The word "more" is spelled the same as usual, but the word "unviewable" has some unique spelling characteristics. The prefix "un-" indicates negation, so the word "viewable" becomes "unviewable" to mean "not able to be seen or viewed." The "-eable" suffix is replaced with "-able" to maintain the pronunciation of the word. Therefore, "more unviewable" means "even less able to be seen or viewed."
