One of the hardest things about learning a new language is figuring out the syntax, or the basic rules for the way that words and phrases should be arranged in a sentence in order for it to make sense.
Syntax isn't necessarily something you think about when you're speaking, but the order of words in a sentence can make a huge difference to its meaning. If you aren't convinced, try telling a waiter that you'd like "a slice of dessert for cake." And then, as the waiter stands there looking confused, try explaining that you don't think "important is very syntax."
