Watashi (私) means "I" or "me." It is the most common and polite way for anyone, male or female, to refer to themselves. You can use it in almost any situation, from formal to casual, making it very versatile for self-introduction or stating your actions. Example: 私は学生です。(Watashi wa gakusei desu.) = I am a student.

自分を指す一番一般的な言葉です。男女問わず使えます。例：私は学生です。
