Speaking Fluently in Daily English

Simple words and grammar is enough to speak fluently in daily English. Passive vocabulary, what you understand needs to be bigger because see, it's, there's an advantage in active vocabulary. You decide, right? So you can just choose the most common words and just use those. That's fine. But when you're listening, see, you don't decide. The other person decides and you never know what they're going to say exactly. And so this is another reason why you're listening vocabulary has to be a lot larger than your speaking vocabulary.
