How to add an alias to a URL?

Hi,

I’m new to WordPress and I would like to know how to add an alias to a WordPress URL.

For instance, on my WordPress site I have some content with a URL in the form:

https://mysite.mydomain.com/something1/something2/something3/

and I would like it to be accessible from this URL and ALSO from an alias in the form:

https://mysite.mydomain.com/something4

Is it possible to do that from WordPress?

Thanks ??
