Questions & Answers about Аккуратность в тетради не только радует учителя, но и помогает мне повторять правила.

What does Аккуратность mean here?

Аккуратность means neatness, tidiness, or carefulness. In this sentence, it refers to neat work in the notebook: clear handwriting, organized notes, clean presentation, and generally careful written work.

Why is it в тетради?

В тетради means in the notebook.

The preposition в can mean either:

• into
  • accusative, when there is movement
• in
  • prepositional, when talking about location

Here there is no movement, just location, so Russian uses the prepositional case:

• тетрадь = notebook
• в тетради = in the notebook

Why does тетрадь become тетради?

Because тетрадь is in the prepositional singular after в.

Its basic form is:

• тетрадь = notebook

After в in the sense of in, it changes to:

• в тетради

This is normal for many feminine nouns ending in -ь.
