Idioma Ruso 

Charles V, the Roman Emperor, used to say that one should speak Spanish with God, French with friends, German with enemies, and Italian with the female sex. But if he had been skilled in Russian, he would, of course, have added that one could speak it with all of them, for he would have found in it the magnificence of Spanish, the vivacity of French, the strength of German, the delicacy of Italian, and in addition the richness and conciseness of Greek and Latin.
