Past events and things happened or existed before the present time.

You use past to talk about a period of time that has just finished. For example, if you talk about the past five years, you mean the period of five years that has just finished.

You use past when you are stating a time that is thirty minutes or less after the hour nearest to the present time. For example, if it is four o'clock and you say that you are leaving at twenty past, it means that you are leaving at twenty past four.

If something goes past, it comes near you and then keeps moving, so that you are then behind it.

The past is the time before the present, and the things that have happened.

Your past consists of all the things that you have done or that have happened to you.

If you accuse someone of living in the past, you mean that they think too much about the past or believe that things are the same as they were in the past.

You use past when you are stating a time that is thirty minutes or less after a particular hour. For example, if it is twenty past six, it is twenty minutes after six o'clock.

If it is past a particular time, it is later than that time.

If you go past someone or something, you go near them and keep moving, so that they are then behind you.

If you look or point past a person or thing, you look or point at something behind them.

If something is past a place, it is on the other side of it.

If someone or something is past a particular point or stage, they are no longer at that point or stage.
