So and Such

Download this explanation in PDF here.

We often use 'so' and 'such' to mean 'very' or 'really'. It makes the sentence stronger and shows that there is a high level of something.

We use 'so' before an adjective or adverb (without a noun).
  • She was so beautiful (= she was very beautiful).
  • He ran so quickly (= he ran very quickly).
  • The food was so delicious (= the food was really delicious).
  • The children spoke French so well (= the children spoke French very well).
We use 'such' before a noun or an adjective + a noun. If there is 'a' or 'an', it goes after 'such'.
  • She was such a beautiful woman (= she was a very beautiful woman).
  • NOT: 'she was a so beautiful woman'.
  • NOT: 'she was a such beautiful woman'.
  • He got such a good time in the race (= he got a very good time in the race).
  • It was such delicious food (= it was really delicious food).
  • The children spoke such good French (= the children spoke really good French).
When we use 'such' directly with a noun, it's often a noun that shows our opinion.
  • He's such a genius! (= he's a real genius / he's very clever).
  • You're such a teacher! (= you act in a typical way for a teacher).
We don't use a word like 'this' or 'those' or 'your' or 'his' before 'so' and 'such'. 'So' and 'such' come directly after the verb.
  • NOT: This so beautiful city. (Instead say 'this city is so beautiful'.)
  • NOT: Your so helpful friend. (Instead say 'your friend is so helpful'.)
We can use 'so... that...' and 'such... that...' to show that there is a certain result. (We can't use 'very' or 'really' in this way.)
  • It was so cold that the pond froze (= because it was very cold, the pond froze).
  • She felt so tired that she fell asleep on the train (= because she was very tired, she fell asleep on the train).
  • It was such an expensive meal that he didn't spend any money for the rest of the month (= because it was a very expensive meal, he didn't spend any money for the rest of the month).
  • They have such a lot of books that they need to store some of them in the garage (= because they have really a lot of books, they need to store some of them in the garage).
We can drop 'that' when we use 'so' and 'such' in this way.
  • It was so cold the pond froze.
  • She felt so tired she fell asleep on the train.
  • It was such an expensive meal he didn't spend any money for the rest of the month.
  • They have such a lot of books they need to store some of them in the garage!
We can use 'so' and 'such' to mean 'to this level' or 'as ... as this'.
  • He isn't usually so late (= he isn't usually as late as this).
  • I don't often drink such a lot of coffee (= I don't often drink as much coffee as this).
We use 'so' before 'much / many / little / few' with and without a noun. This shows that the amount is really a lot or really little. As usual, we use a plural noun after 'many' and 'few' and an uncountable noun after 'much' and 'little'.
  • I ate so much.
  • I ate so much cake.
  • He had so many.
  • He had so many books.
  • Why did you eat so little?
  • He had so few friends that he was very lonely.
We can use 'such' before 'a lot (of)'. Again, such comes before 'a'. (We sometimes see 'such a little + noun' but that is when 'little' is just a normal adjective: 'this is such a little flat'.)
  • He has such a lot of books.
  • I ate such a lot of cake.

Other Uses of So and Such

Here are a few more idiomatic uses of 'such' and 'so' that are slightly different from what we have already seen.

Such + noun = a certain type or kind of (this is quite formal)
  • I'd never heard such music before. (= I'd never heard this kind of music before.)
No such + noun = the noun doesn't exist
  • Ghosts? There's no such thing!
As such (formal) = in the normal meaning of the word. We usually use this in the negative ('not as such')
  • We're not going to have dinner as such, but there will be plenty of snacks. (= we're not going to have a normal dinner, but ...)
  • A: Is Lucy your boss now? B: Not as such (= not exactly) but she does work for the same company.
Such as = for example / like
  • A: We should get a film for tonight. B: Such as? (= please give an example of a film)
  • Cities such as London are becoming more powerful politically (= cities like London ...).
And such / and so on = and more similar things
  • He likes winter sports – snowboarding and skiing and such.
  • He likes winter sports – snowboarding and skiing and so on.
So = a certain amount / size
  • It was so big (= it was the size I'm showing you with my hands).
  • There's only so much time (there's only a certain amount of time).
So = something that has already been said
  • A: Is dinner ready? B: I hope so (= I hope that dinner is ready)
  • Is that so? (= is that right?)
Or so = approximately
  • I think there were fifty people or so at the party (= I think there were approximately fifty people at the party).
