How to store cities in different languages?

Question

MySQL

There is a base, let's say id city_name
The user must select his city, let's say through select2 with ajax. I entered 3 letters, the request went, like 3 letters got out, json returned. Everything is clear here.
Up to the point that cities can be in different languages. And initially there are 3 of them, and then they will be added. Do in the database city_name_ru city_name_en, etc. not very convenient. Multilingualism itself is implemented by regular means of yii2.
Who faced, what are the developments on this topic?
Create different databases for each language with id city_name? What would id match?

Answer 1

Separate table (`city_id`, `language`, `city_name`), primary key (`city_id`, `language`)
