So and such
What’s the difference between so and such? Put simply, we must use ‘such’ with a noun (with or without an adjective beforehand), there must always be a noun. It’s also very common to use the articles ‘a/an’ before the noun. We use ‘so’ before an adjective or an adverb, alone. (Never use an article with ‘so’).
“Such” with a noun, articles and no articles
- David and Maria are my favourite students, they’re such good people.
- I’m such a nice person, I don’t know what to do with myself.
- You’re such an idiot.
- We had such a good time, sad that we’re leaving now.
“So” with adjectives and adverbs
- You are so idiotic, it’s insane.
- I’m so tired of all this nonsense.
- How was the class? It was so good, I can’t wait until tomorrow!
- Why do you have to speak to me so rudely?
