Common Mistakes
- ✗Using such before a bare adjective with no noun: "It was such interesting." → should be "It was so interesting."
- ✗Using so before an article + noun: "It was so a good film." → should be "It was such a good film."
- ✗Dropping the article with a singular countable noun after such: "such good idea" → "such a good idea."
- ✗Mixing up much and many: "so much people" → "so many people" (people is countable plural).
Tips
- ✓Quick test: if a noun follows, use such; if only an adjective/adverb follows (no noun), use so.
- ✓The that-clause is often dropped in speech but kept in writing: "so tired (that) I fell asleep."
- ✓With plural nouns used generally, such drops the article: "such nice people" (not "such the nice people").
Advanced Notes
Native speakers frequently drop "that" in casual speech ("It's so late I have to go") and often use so or such purely as an intensifier with no result clause at all, especially in exclamations: "I'm so happy!" or "It's such a beautiful day!" Don't confuse so...that (cause and effect: "so tired that I slept") with too...to (inability: "too tired to walk") — they look similar but express opposite logic. In formal writing, the that-clause is usually kept explicit for clarity.
