How to display pages in a specific language?

Question

WordPress

I want functionality on a wordpress site that allows you to select the display language. Articles and pages must be written in several languages ​​(Eng, Rus, etc.). Depending on the choice of language, the user will be presented with a version of the article in a specific language. It should be possible to change the language on the fly, so that while already viewing the page, you can change the display language.
Are there already existing plugins and solutions?

Answer 1

WPML or free alternatives
