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’).
