The film is based on Anthony Burgess‘ novel about young Alex Delarge and his droogs who go around tolchocking people and partaking of the ultraviolence and the old in-out-in-out.

Yes, the language is a futuristic mix of Russian, slang and made-up words that Burgess employed so that the futuristic language employed would never sound dated. He called it Nadsat. By the end of the film, for better or worse, you will understand the language.

Note: This may be too detailed for those who have not seen the film, so I advise reading it after a viewing.

Alex likes violence, sex, and Beethove... qalǵanyn oqý.
