I’m sorry, I’m not finding what I *think* you’re alluding to or the ‘o’ spelling.
Perhaps a link to the spelling, etymology, exegesis you’re in agreement with?
The ‘o’ ending is singular.
For something that is supposed to be easy and self interpreting for the reasonable man this sure is complicated and confusing.
I really, really, really want to get to the truth. I closed my eyes real hard (like a Televangelist during the passing of the collection plate), clicked my heels three times, and looked for evidence to corroborate Editor's claim, but it still comes up hollow.
