I haven’t written much about Latin in a while. Well, in a year. Anyhoo, that is beside the point. The point is: the third declension is a frustrating mess because it is basically the wastebasket of all declensions. I mean, yes, all these nouns are declined similarly, which tells us that they are, in fact, a family. But the declension itself is full of masculine, feminine, and neuter nouns, and telling the difference is complicated.

When my son and I were debating over this again, I decided to make a flow chart to prove that I was right help my son in his studies. I actually printed it out on index paper to make a sort of bookmark to rub it in be even more helpful. I’m sharing it here, but please note that there are some exceptions. I noted that on the chart, but I wanted to point it out, just in case. However, comma, this chart will help you determine the gender of the vast majority of third declension nouns, so it’s still useful.
So here you have it:

You are a hero!
Why, thank you. It’s my only super power. 😉
hi, I’m just wondering why ‘or’ is in ERROR and SOX, because if it ended in ‘-or’ i wouldn’t have to check SOX, so I’m a little confused…
sorry if I sound rude, I’m just confused.
OMG I’m so sorry, I’m only now realising that you meant or as in the conjunction…
sorry 🙁
Ha! It’s quite all right. 🙂
I love this chart and would like to use it in my class. However, I cannot get it to print correctly. Do you have this as a single file? Thank you!!!
If you fill out the form at the bottom of the post, it’ll email you a printable PDF that has it formatted as two bookmarks. 🙂
Thanks! I’m just now seeing this. 🙂
You’re welcome! 🙂
Brilliant! I will be using this to teach my beginning Latin students. Thank you.
