"Saying "the Same" in Russian.
To say "the same N" in Russian, you need only add the particle же after the appropriate form of the demonstrative pronoun. For example, if someone snooty says that s/he saw the latest French film, Я видел(а), ты знаешь, тот французский фильм "I saw, you know, that French film", to put them in their place retort: Я видел(а) тот же фильм "I saw the same film"—you just add же to the тот. If some tells you that they've been to Monte Carlo, all you have to say is Я был(а) там же: "I've been to the same place". Neat, huh? And, as usual, simplissimo!" - Some Very Demonstrative Russian Pronouns
