When you’re learning Spanish, lots of rules are important to see once, then forget. How adverbs work, is a good example. When I did a little Googling, I saw there are five ways adverbs are used. Ugh. More rules. Then, after a few seconds, I noticed something… adverbs in Spanish, work exactly like they do in English! There’s NO REASON to memorize five rules when you can just use them as you naturally would. But like I said, this is an example of a time when it’s good to see the rules once, then forget them and just use them. In this case, knowing isn’t just half the battle, it’s the whole enchilada.
