Question

What is a russian gymnasium?

Answer 1

Russian Gymnasium - A general-education secondary school preparing students for university. Gymnasiums originated in Germany in the 16th century.

Answer 2

It can be a preparatory school for higher studies (something like a college or advanced high school).

Actually, they exist in many countries, including in the USA (where they may be called a different name, something like 'magnet schools' maybe?).

In English, the word is now restricted to the physical education aspect and to the convocation room (which we use for physical education and indoor sports)
