I managed to go through the pronoun paradigms. I was confused on the demonstrative pronouns. I understand that the se set can function as the definite article. But as demonstrative pronouns, do that set and the þes set work in the same way as MnE demonstrative pronouns. The example given on page 18 of hē sorgaþ ymb þā uses the plural accusative of se where in MnE we would use a personal pronoun. Furthermore, there exists a 3rd plural accusative personal pronoun hīe as well as a 3rd singular neuter personal pronoun. So, I guess I'm confused on when to use the demonstrative pronouns - particularly the non-nominative ones - and when to use the 3rd singular neuter or 3rd plural personal pronouns.
This confusion made me realize a possible disadvantage to continuing with AGtOE. It seems like the approach of the book is to learn various grammatical and syntactical paradigms before seeing any examples of usage of those paradigms. If I remember the "How to" section properly, at some point we are encouraged to read through the prose and verse texts, where we will see all the paradigms we've learned in action. But that's a lot of grammar/syntax rules to memorize before seeing even one example of actual usage. In this regard, I could see how a more modern resource like Teach Yourself would be better because they give examples along with the paradigms. I'm not saying we have to switch; I guess it's just, for me, this type of approach is new to me. I usually have used resources that give at least one example for any new paradigm or rule, especially for things like inflection tables. Maybe we could come up with our own examples of usage? I know that would help me a lot.
