We often use the words so and such in the meaning of "very", "really".
I am so hungry! (= I am really hungry)
You look so beautiful! (= very beautiful)
It was such a difficult test! (= a really difficult test)
We had such a good time in Spain! (= we had a very good time)
Such + noun, so + adjective/adverb
It is important not to confuse "so" and "such".
"Such" goes together with a noun. There might be an adjective in between, but the noun is always present:
- such + noun
- such + adjective + noun
"So" goes with adjectives (e.g., nice, big, dark) and adverbs (e.g., well, quickly, poorly), there is no noun:
- so + adjective
- so + adverb
It was such a wonderful morning! That morning was so wonderful!
Your friends are so kind! I don't have such friends.
I've never heard such a song before. The song was so touching.
Mike cooks so well! He can cook such delicious dishes!
So + much, many, little, few
We use "so" with the words much, many, little, few to make them stronger. We might have a noun after these words, but it doesn't matter. We say "so" anyway.
