Hello!
The ‘Page’ word comes from WordPress itself. It translates automatically to the site language set at “WP Admin > Settings > General > Site Language.” I recommend setting that to the language you’re writing the site in. This will change the site’s HTML language attribute, which conveys your site’s language to search engines for language-targeted indexing. It also allows browsers to suggest automated translation options.
If you prefer to manage your website in English, you can change the “Language” setting at “Users > Profile” independently.
I do not recommend using only a number for pagination because that doesn’t convey pagination to users or Google.
