Questions & Answers about Eu anoto todas as tarefas no caderno.

What does anoto mean, and why is this verb used here instead of escrevo or registo?

Anoto comes from the verb anotar, which means “to jot down” or “to note.” It implies briefly recording information.

• Escrevo (“I write”) is more general and can mean writing at length.
• Registo (from registar) often suggests making an official or formal record.

Here, anotar is the natural choice when you casually note tasks on paper.

Why is Eu included? Could we omit it?

Portuguese is a pro-drop language: the verb ending already indicates the subject.

• Anoto todas as tarefas no caderno. is perfectly grammatical without Eu.
• Including Eu adds emphasis or clarity (“I do it” as opposed to someone else).

Why do we say todas as tarefas instead of todas tarefas or simply todas as tarefas?

In Portuguese, plural nouns generally require the definite article:

• todas is a pronoun meaning “all,” and it pairs with the article as to agree in gender (feminine) and number (plural) with tarefas.
• Dropping as (todas tarefas) sounds ungrammatical.

What does no caderno mean, and why this form?

No is the contraction of em + o, meaning “in the” or “on the” when referring to a masculine singular noun.

• em o caderno → no caderno
  If the notebook were feminine (a agenda), it would be na agenda (em + a).

Could we use another preposition instead of em here, for example sobre o caderno?

Not really.

• Anotar algo sobre o caderno could imply writing on top of its cover or surface, not inside.
• Em (in/on) is used because you’re recording the tasks inside the pages.

How would you turn this sentence into a question in Portuguese?

You can invert the verb and subject or add a question particle:

• Anotas todas as tarefas no caderno? (informal, using tu)
• Anota todas as tarefas no caderno? (informal, você form)
• Você anota todas as tarefas no caderno? (full form, more neutral)
  You could also add Não é? or Certo? at the end for confirmation:
• Você anota todas as tarefas no caderno, certo?
