I don't want to learn just words. I want to learn phrases. I'm learning the language to communicate. While, having the vocabulary helps you in a bind, it's much easier, and politer, to ask for what you want in a sentence. For example, today, I went to the grocery store for some marrow bones. I feed them to my dogs as treats and/or teeth cleaners. They had four packages but I wanted more. So I went to the butcher and said ¿Usted tiene mas? I could have said ¿Mas? but it wouldn't have been as polite. Sure, I would have gotten more by just saying the word but I want to learn the language proper
