Questions & Answers about Jeg håper at tannbehandlingen ikke blir for dyr.
Yes. at is a subordinating conjunction that works like English “that”:
- Jeg håper at tannbehandlingen ikke blir for dyr.
= I hope *that the dental treatment doesn’t become / won’t be too expensive.*
Just like in English, “that” is often optional:
- Jeg håper tannbehandlingen ikke blir for dyr.
(perfectly natural, especially in speech)
So:
- håper at … = hope that …
- at can be dropped in many everyday sentences, but keeping it is never wrong.
