Removing word ‘category’ from url or changing it

yes, you can change the word category.

Settings / Permalinks / Category base

Thanks, and as for removing the ‘category’ segment from the url entirely, is it possible ?

There is a plugin that allows this. I’ve never used it. Search on the plugins page https://www.ads-software.com/extend/plugins/

Thanks! I found it very quickly. There’s one last thing I was wondering and it seems a little more difficult for me. I have one single category, level [0], that is the parent of all other categories, let’s say they’re all of them level [1]. On the ‘single’ page, I want to use the previous_post_link and next_post_link tags, but I want the links to work only within the child categories that are level [1].

Is there a plugin I should use for that or can the tags be instructed to do that ? So far, there’s only the option to display prev/next links for any preceding or following post that belongs to any category the post being viewed belongs to with ‘Previous in category’, be it parent or child or grand-child or grand-grand-child. I would like to restrict the prev/next links to work on the first-child level exclusively.
