Latina Christiana 1 - 2nd Second Declension Neuter

[Nadia]

Hi Friends, I've got a question to confirm something I'm thinking. We are in Lesson 12 of LC1, and today my daughter pointed out that the "i" listed as the plural ending after each vocabulary word is incorrect - that it should be "a", since this is the appropriate "plural" ending for these words. At first I thought the words were 2nd Declension Masculine words, but when I looked at the list in the back (listed by grammar form), the vocab of this lesson is in the 2nd Declension Neuter list. This means the plural ending should be "a" for the Nominative case.

Isn't this right? If so, the book is incorrect.

We are relatively new to Latin so I did want to check with you "pros"!

Thanks,

Nadia
