What is the plural of "ascertainment"?
What is the plural of "ascertainment"? Do you add an "s" at the end? Do you add nothing? Is it even countable? Can you have two ascertainment(s)? I looked in the Oxford English Dictionary and it wasn't much help.
The reason I ask is that Word keeps telling me "ascertainments" is a GRAMMAR error (and yes, the verb agrees with the subject). I can't figure out why.
