How to correct apparent mistakes in Office 2010 main dictionary?

[Liz1]

I was just typing something which Word 2010 did not recognize. My spelling of "monosaccharides" is correct, but Word offered "monosaccharaide's" and "monosaccharaide," both of which are incorrect spellings (at least in the U.S.). I checked the custom dictionary to see if at some point I had inadvertently marked these spellings as correct, but they did not appear in the custom dictionary, leading me to believe that the misspellings are in the main dictionary. Is there a way to correct this?
Thanks in advance for your help.

I don't know if will work in your program but you could try this.
Spell the word as you want it. Right click on it. If it gives you the option (add to dictionary) tick on it.

I think you might find that it was addressing 'Grammatical' (in particular punctuation) rather than 'spelling' issues. i.e. the position of the apostrophe...

FYI "monosaccharides" is the plural of "monosaccharide" a sugar.
