The original 1991 translation of Burgess's book into Russian solved the problem of how to illustrate the Nadsat words by using transliterated, slang English words in places where Burgess had used Russian ones (i.e. "droogs" became "фрэнды" ("frendy"). This solution was imperfect as it lacked the original abstractness. Borrowed English words with Russian inflection were widely used in Russian slang, especially among Russian hippies in the 1970s–1980s. Since the 1990s anglicisms in Russian have been common particularly regarding computers and programming. Future translations would simply use the original untranslated Nadsat terms.
