Thank you for using the Jiskha Homework Help Forum. If the following doesn't help, I'll be happy to share the Latin sites I have:

6. (part II of #5): http://ancienthistory.about.com/od/nouns/f/LatinEndings.htm
Thank you SraJMcGin! I appreciate your time and effort in helping me improve my studies in the Latin language.
