So or Such?
Both so and such add emphasis ("very") to the following expression, but they are used before different types of words.
So + adjective/adverb
- He is so nice.
- It was so cold that I stayed in bed.
- She was so tired that she fell asleep.
So is also used with much/many/little/few before a noun:
- so much bread, so many friends, so little time, so few things
Such + noun (with or without an adjective)
- such horrible weather
- such silly people
- I don't know what to do with such information.
Such a/an + adjective + singular countable noun
Before a singular countable noun, we need the article a/an between such and the noun.
- He's such a nice person.
- It was such a good car that I couldn't sell it.
- It is such a pity that you couldn't be there.
Common mistake to avoid
Never say a such – the word order is always such a, never a such.
