While "arrival" can be used as a verb, it is also a noun that represents the act or fact of arriving.
Here's an example:
* Concrete: The train's arrival was delayed.
* Abstract: We celebrated the arrival of the new year.
In the first example, "arrival" refers to the specific event of the train coming in. In the second example, "arrival" is used in a more general sense to represent the concept of reaching a certain point in time.
