I took German back in high school but I don't really remember anything about it. How can you read if you don't at least have an idea of what each word or phrase means? I'm a native born English speaker, and I occasionally have to look up English words if I have no idea what they're supposed to mean. It's one thing if it's an obvious random word for a gadget such as doohickey. I can't imagine reading a foreign language and surmising what a word means without a definition.
