Knowing when to use estar and ser

Question

When to use "estar" and "ser"?

Answer 1

Welcome.

Have you looked in the grammar or learning section here yet?

Check it!

Answer 2

You can also simply Google ser and estar, you'll find dozens of pages to help you out.

You know, you reminded me of a very good book on this subject:

Spanish Verbs: Ser and Estar (Hippocrene Language Studies)

I've been looking it over again lately. I didn't pick up a copy until long after I had many struggles with ser and estar though. I wish I had known about it when I first started learning Spanish, it would have helped me out a lot.

Does anybody here own a copy? I'd love to hear your thoughts about it as well.
