IN THE BEGINNING is usually preferred alone and followed by a comma. It covers a much LONGER, INDEFINITE PERIOD OF TIME and for many English speakers it resonates with religiosity and, therefore, it is used less often than "at the beginning." - In the beginning, I liked my job, but now I don't. - In the beginning, God created the heavens and the earth... AT THE BEGINNING is followd by OF and it is used together with a noun such as: year, book, century, show... it also describes a PRECISE MOMENT. - At the beginning of the book the main character is described. - At the beginning of the year, I promised myself not to smoke anymore. I hope it helps :-)

Hello Nazanin, IN THE END: is used mostly as an idiom that means "finally," "after a long time," or, "when everything is considered." It is often followed by a comma. Here are some sentences with this idiom: - I studied a lot and, in the end, I passed the exam. - In the end, what the world really needs is love. AT THE END: is used in the idiom "at the end of the day." It is most commonly used as a phrase followed by OF to refer to the end of something specific: a physical object, a period of time, an event, a place, or something more abstract, such as one's patience. Here are some sentences with AT THE END + OF: - I can see the light at the end of the tunnel. - I'm at the end of my patience. I hope it helps :-)
