Questions & Answers about أنا أساعدها وهي ترتب المائدة قبل أن تصل الضيفة.

Why is أنا written if أساعد already means I help?

Because Arabic verbs usually already show the subject. أساعد by itself means I help / I am helping. So أنا is not required here.

Adding أنا gives emphasis, contrast, or extra clarity. In other words:

• أساعدها = completely normal and grammatical
• أنا أساعدها = I am helping her / I am the one helping her

How is أساعدها built?

It has two parts:

• أساعد = I help / I am helping
• ها = her

So أساعدها literally means I help her.

This is very common in Arabic: object pronouns are often attached directly to the verb instead of being separate words.

Do ها in أساعدها and هي in وهي ترتب refer to the same person?

Yes, most naturally they do.

• ها = her
• هي = she

So the sentence is talking about one woman: I help her, while she arranges the table...

Arabic often repeats the subject with a separate pronoun when a new clause begins. This helps make the reference clear.
