أنْ + الفعل المضارع
After verbs like قرر and حاول, Arabic often uses أن + a present-tense verb to mean 'to do something' or 'to continue doing something'. It is a very common pattern for decisions and attempts. You can reuse it in sentences like: قررتُ أن أدرس اليوم. In the story, the same pattern appears in قررت أن تكمل and حاولت أن تنظف.
قررتُ أن أدرس اليوم.
I decided to study today.
