Many of my students get confused about how to use the words “so” and “such” correctly. Sometimes they say things like, “My friend is so nice guy.” or “It is such hot today.” These sentences are completely wrong in terms of grammar.
When we use the word “so”, it is followed by an adjective. When we use the word “such”, it is followed the article “a” or “an”, then by an adjective and finally, by a noun. Sometimes there is no adjective in the sentence at all. For example:
My friend is so nice.
My friend is such a nice guy.
My friend is such a gentleman.
It’s so hot today.
It’s such a hot day today.
It’s such a scorcher today.
Harriet is so intelligent.
Harriet is such an intelligent woman.
Harriet is such a genius.
In case you’re wondering, the word “scorcher” in the sixth sentence is a casual word that refers to a very hot day. The word “scorch” has a similar meaning to the word “burn”.
It’s important to note that when we use “such”, we only use “a” or “an” in the sentence if the noun is countable. If the noun is uncountable, we must drop the article. For example:
This is such good wine. Where did you get it?
My guidebook gave me such useful information.
We had such beautiful weather during our vacation.
It’s also possible to use “so” with an adverb. For example:
My sister dances so well.
The construction job was done so badly.
Please note that we cannot use “such” with adverbs.
