How to show tag name in URL

An issue with doing this is that WordPress might not understand how to process
‘mytagname’. It could be a tag, some other taxonomy or even a page/post slug.

If there is a way to clearly differentiate tags via a regular expression, you can use the add_rewrite_rule() function to set this up where all URL paths matching /[a-z]+ would be rewritten to tag/[a-z]+.

There are examples at the bottom of the docs. You will need to flush permalinks for the changes to take effect.

To achieve this, I had to add the following lines to functions.php. You could create a child theme to preserve these changes across theme updates.

add_action('init',  function() {
    add_rewrite_rule('^([a-z]+)[/]?$', 'index.php?tag=$matches[1]', 'top');
});

Then I changed the other permalinks in Settings > Permalinks to ensure that none of them matched this regex ^([a-z]+)[/]?$ and clicked Save Changes to flush the record.
