my hierarchy is gone

i was playing around in unity and i exited my hierarchy so i could make the screen bigger. i can’t get it back and don’t know how to so please help!

I assumed you closed the hierarchy tab. To reopen it, press the Window menuitem at the top of your screen, then select Hierarchy. Alternatively, press Ctrl-4. Then just drag the reopened hierachy window to where ever you want it to dock.

You can also use the preset layouts, all of which contain the hierarchy window. Just click on the “Layout” drop-down menu in the top right corner of the Unity Editor.
