Is there a list of vocab words with their definitions for Y4U2?

Yep! It was finished after many people had already downloaded Unit 2, however, so thay be why you missed it. You have two ways to get it:

1) download the newest version of the "Tapestry of Grace" from the Content piece of our Download Center. This will replace what you have with the newest version, which includes the glossaries.

OR, if you don't want to download now (you'll have to download again when Unit 3 comes out anyway)

2) you can access them temporarily from the online Year 4 Loom.
