SPELL CHECK ins't even an OPTION in my Adobe Acrobat Reader DC!

I am filling in a PDF form by typing into it, which works 100% fine.   But spelling errors are not flagged and there is NO spell check option anywhere! Not in EDIT. Not if I search for "spell" under options or whatever it's called.  If I look under Adobe Plug Ins it says Acrobat Spelling plug-in is loaded.  BUT THERE IS NO SPELL CHECK OPTION!!!  UGGGHHHH!!
