So/ Such… that , too/ (not) enough … to

Understanding how to connect ideas is an important part of speaking and writing in English. In this lesson, we look at two very useful structures: so/such… that and too… to / (not) enough… to. These help you explain reasons, results, and limits in a clear way.

1. SO / SUCH … THAT

We use so and such to talk about a cause, and that to show the result.

👉 Grammar

  • so + adjective + that
    • I’m so tired that I want to sleep right now.
  • such + a/an + adjective + noun + that
    • It was such a good movie that I watched it twice.

👉 When to use SO

Use so before an adjective or adverb.
The people were so friendly that I felt relaxed.

👉 When to use SUCH

Use such before an adjective + noun.
It’s such a beautiful day that I want to go outside.

Examples

  • The problem was so big that I needed help.
  • She has such long hair that everyone notices her.

2. TOO … TO / (NOT) ENOUGH … TO

These structures explain that something is more or less than we want or need.

👉 TOO … TO

Use too + adjective + to + verb
→ shows something is more than you want or a negative result.

It’s too cold to go for a walk.
He was too nervous to speak.

👉 (NOT) ENOUGH … TO

Use:

  • not enough + noun
    There isn’t enough time to finish.
  • adjective + enough
    She isn’t strong enough to lift it.

→ means you don’t have as much as you want.
