Editor’s Corner: Latin Plurals and a Gardener with a Sense of Humor

When I was a kid, I remember my mom and dad correcting my plural endings for certain Latin words. “It’s not cactuses, it’s cacti.” “A lot of mushrooms aren’t funguses, they’re fungi.” So, like an obedient child, I learned appendix/appendices, criterion/criteria, curriculum/curricula, etc.

Imagine my horror, then, when I was double-checking the proper plural of apex or something, and I found that the rules had changed over the past forty years. I don’t remember if it was the Chicago Manual of Style or one of the books they published, but I learned that there is a movement to get away from the Latin endings of the words. The thought is that since we’ve adopted the words as part of English, we should apply English rules to the plural. Conversely, if we were speaking Latin, then we’d use the Latin rules for the plural words.

I’m sharing chunks of the list over a couple of days, but if you want to see the complete list in order, go ahead and check out Daily Writing Tips. You can see from the list that both English and Latin endings are given, if they exist. You can be the judge of which endings you still hear more often.
