Using Word 2011 on OS X Mavericks, I frequently produce documents using both English and polytonic Greek (i.e. ancient Greek with accents and breathings, from before the spelling reforms of 1982). Word 2011's spell check treats the Greek as English and incorrectly underlines much of the Greek as misspelled.
Even if I type the Greek in using the Greek keyboard Word still treats the Greek as English. If I manually change the language to Greek (highlight the text; tools -> language -> Greek), the errors go away. I would really like, though, not to have to change every bit of Greek manually, since I tend to go back and forth pretty frequently. Is there any way for Word 2011 to automatically detect text using the Greek alphabet and either ignore the text or use the Greek spell checker?
Essentially I'm looking for a way to produce documents using both English and Greek and have Word check the spelling of the English but not the Greek.
