Does "head to" give different nuance from "go to"?
Both "head to" and "go to" express the same intent to get to another place, although they do have a slightly different nuance. To "head to" somewhere implies that someone is just starting to go towards that place, and they may not go straight to that place. To "go to" implies that someone is already going there, and it also implies that they will go straight there and not make any stops on the way. In this way, "go to" is more direct and clear that you are going somewhere, where "head to" just means you'll start going towards that direction. Ex: It's getting late, we should start heading home. Ex: Let's head to the beach. Ex: I need to go to school.
