So vs Such Easy Exercises

The core difference between so and such is what follows them. So goes before adjectives and adverbs when they stand alone: "The weather was so hot" uses "so" because only the adjective "hot" follows. Such goes before noun phrases: "It was such a hot day" uses "such" because the noun "day" comes after the adjective. The simple test: if there is a noun after the adjective, use such; if the adjective stands alone, use so.

With singular countable nouns, such needs an article: "such a lovely surprise" or "such an exciting match." With plural and uncountable nouns, there is no article: "such lovely weather," "such kind people." A common mistake is putting the article before "such" — "a such lovely day" is incorrect; the article always follows "such." Many learners confuse these two words in exams. Remember the simple test: noun present = use such; no noun = use so. Cambridge A2 Key and B1 Preliminary both test this distinction regularly.
