What’s the possessive form?
I think the possessive form of course
is course's,
it keeps appearing with a red squiggly underline in my Google Docs. Too bad Google’s dictionary has no proper format to fill the gaps if I know there should be a better alternative. I’m thinking it’s the latter.
What is possessive form of education?
What should I do instead of calling everyone or everything I have to do?
Does course really is correct? When in doubt, I’ve seen most automated spelling corrections people. Use them as tools and in the way they were intended: not as an authority, but as an indicator of the possibility that you may have made a typo.
