So and such

B1  B1 grammar · lesson 16 of 23

So and such make adjectives and nouns stronger, and with ‘that’ they show a result. Choosing the right one depends on the word that comes next.

So or such?

Both words mean very or really, and add emotion. They are stronger than very and are very common in speaking, especially when we are surprised, happy or annoyed. The difference between them is the word that comes after them.

WordFollowed byExample
soadjectiveThe film was so good.
soadverbHe speaks so quickly.
such a / an(adjective +) singular nounIt was such a good film.
such(adjective +) plural or uncountable nounThey are such nice people. It was such awful weather.

The weather is so hot today.

It’s such a hot day.

Your children are so polite.

You have such polite children.

Why are you driving so fast?

Leo is such an interesting person.

So many, so much, so few, so little

Before many, much, few and little, we use so, not such.

  • There were so many people at the concert.
  • I’ve got so much work to do.
  • Exception: we say such a lot of: We had such a lot of fun.

Result: so… that, such… that

We use so/such… that to show a result. The first part gives the reason, and the that part tells us what happened because of it. In speaking, that is often left out.

The box was so heavy that I couldn’t lift it.

It was such a good book that I read it in one day.

She spoke so quietly (that) nobody heard her.

There was so much traffic that we missed the start.

Tip: Look at the next important word. Is it a noun (day, people, weather)? Use such. Is it only an adjective or adverb (hot, quickly)? Use so. Remember the article: such a nice day, never a such nice day.
