How come "this big" us used at the last of the sentence? for an emphasis? I'd like to know how can I use this.
Great question! "This big" is used at the ending of this sentence to emphasize how big the problem is. You can use "this big" when you are discussing a large problem that you don't know how to solve. You can also use this if you are discussing something that is large in size. Ex: How am I able to carry something this big? Ex: He is a big man. Ex: This is a big problem.
