I'm a pretty old codger myself, but we had great grammar teachers in my day! Verbs have voice, tense, mood, sometimes number; nouns have case, number and/or gender -- no voice.
Did you ever learn sentence diagramming in grammar school? I had it in seventh grade and for a while couldn't read a book (even Anne of Green Gables, a favorite!) without mentally diagramming the sentences as I read!
My lost answer was better . . .:(
Oh my, sentence diagramming! That nightmare was revisited in Graduate School when I had to take Modern English Grammar as a requirement toward my Masters.
