Okay, the following is a little lesson in grammar (because it irks me when people don’t use it correctly!!!!!)
Your – it is yours, it belongs to you.
E.G. Is this bag yours?
Your brother sat next to me on the bus.
You’re – An abbreviation for you are.
E.G. You’re and absolute legend.
You’re going to be late if you don’t get a move on.
Now let’s put both words into one sentence:
E.G. You’re going to ride your bike to school.
There, their and they’re:
There – Here, there and everywhere. In that place. Right now. In that respect.
E.G. We will go there.
Please put it over there.
There goes the bell for lunch.
There you are wrong.
Their – It belongs to them.
E.G Their bags need to be hung up.
They’re – An abbreviation for they are.
E.G. They’re all going to the fruit shop.
If they’re going outside, they will need sunscreen on.
Affect and effect:
Affect – To have an influence on
E.G. The weather was affecting the play times.
Effect – A result brought about by a cause.
E.G. The effect of the weather was that the tree fell over.
Let’s put them both into one sentence:
We know that the effect of air conditioning will affect the temperature in the room.
