Homophones are words that are pronounced the same but have different spelling and meaning.
There, T-H-E-R-E, means over there, that place. They’re, means they are. You use an apostrophe for this, drop the A and it becomes they’re, they are. Their means it is their things, their stuff. Another example of homophones is whole and hole. Whole is the entire object. Hole means like a ditch, or a trench. Our last example is allowed and aloud. Aloud, A-L-O-U-D means saying something out loud. Allowed means that you have permission to do something.
