So and such have similarities in meaning but they are different in use. We use so with an adjective without a noun. For example: so high, so beautiful, so clever etc. Unlike “so”, such is used before an adjective with a noun. For example : such a high mountain, such a beautiful girl, such a clever boy, etc. Let’s see them in sentences :

1. I like Jack and Sue. They are so nice.
2. I like Jack and Sue. They are such nice people.

So and such are used to make the meaning of the adjective stronger. They mean really. 

• So nice means really nice.
• Such nice people means really nice people.

So …That And Such …That

We often use so … that and such…that to combine two sentences. The first part is a cause. The second part is a result. Let’s see the following tables.
