Answer 1

text_domain is a distinction inside WordPress that allows you to see which plugin or theme text comes from. The text domain can be any string that you want but as a best practice it should be a machine name of the theme or plugin you are building.

So if I had a plugin named MyPlugin I would translate text using any of the WordPress translation functions like:

print __("Translateable Text", "MyPlugin"); _e("Text that is translated then echoed", "MyPlugin");

For WordPress to render these strings in another language, in WordPress 4.0 and above, you can change the language at Settings > General > Site Language and your site will show the text in that language if available.

You will need language files for the language that you wish to change to, and if a plugin or theme doesn't offer a translation for your chosen language it will be rendered in the default language.

There are many tools and plugins for editing the .po/.mo files that hold the translations in WordPress. Some of those can be found in the WordPress translation handbook .
