I guess it's kind a spectrum: 1. Wordpress in a default install, definitely not static 2. Wordpress with a caching plugin, wherein the cache is generated on request is only expired on page update. Still not really static 3. Wordpress with a caching plugin, where the cache is created on page edit but still served by the PHP code 4. Wordpress with a caching plugin, where the cache is created on page edit but pushed to another server to serve (i.e. using it as a headless CMS) 5. Your standard markdown -> html static site tool To me step 4 is when the resulting site crosses over to a static site.
