Yes, it really is all about context. Given so many forms for each word, you can only expect that some of them are going to coincide with forms that have completely different meanings or even other words altogether. :-\<br /><br />If you are not catching onto this from however much reading your book gives you, I would highly recommend that you pick up a beginner reader. What works really well is to learn from a good, hard book, and practice just reading (with or without translating) from a fairly easy book. It will do wonders for your comprehension. Most textbooks only offer a little bit of reading and some exercises, but going over a few pages of easier Latin is a great exercise too.
