Can I add a blog inside a subsection of my WP site?

Hi there,

I’m relatively new to WordPress, and have so far managed to build a site with pages and my own theme.
I now want to add a blog inside one of the sections, but I can’t seem to find any resources on this topic.
Currently my test blog pages are all showing up at root level (e.g. https://myNewSite.dev/my-first-blog), but ideally I’d like it to be shown under one of the sections (e.g. https://myNewSite.dev/my-blog-section/my-first-blog), with the section title in the main nav highlighted correctly.

I assume this is possible, but could anyone point me in the right direction? I’m very lost…

Many thanks for any help!
