وبالتالي

In a sentence

• أنا لم أدرس جيدًا للامتحان، وبالتالي لم أنجح.

  I did not study well for the exam, and therefore I did not succeed.

  The word "وبالتالي" here is used to indicate a consequence or result of the previous statement.

• الطريق مغلقة بسبب الحادث، وبالتالي علينا أن نسلك طريقًا آخر.

  The road is closed due to the accident, and therefore we have to take another route.

  "وبالتالي" in this sentence is connecting the cause (the road closure) to its consequence (the choice of another route).

• المنتج لم يكن كما توقعت، وبالتالي طلبت إرجاعه.

  The product was not as I expected, and therefore I requested to return it.

  Here, "وبالتالي" is used to link the description of the product's quality to the resulting action of returning it.
