Shifting in syntax is like playing with Legos!
Imagine you have a sentence that's made up of different blocks (the words). Sometimes, you want to move a block around to make the sentence sound better.
For example, let's say you have the sentence "I ate breakfast this morning." But you want to emphasize that it was breakfast you ate and not lunch. You can shift the word "breakfast" to the beginning of the sentence to make it "Breakfast, I ate this morning." This way, the word "breakfast" comes first, and your listener knows right away what you are talking about.
Or let's say you have the sentence "The dog chased the cat." But you want to put more emphasis on the dog. You can shift the word "dog" to the beginning of the sentence to make it "The dog chased the cat." This way, you're telling your listener that the dog is the most important part of the sentence.
So shifting in syntax is like rearranging the Lego blocks to make the sentence sound better or emphasize certain parts. Easy, right?
