Korean (hangeul)

Hello, Does anybody know how to use the Korean alfabet (hangeul) for Linux? For the time being, I would only need it for word processing. Now I have only a great lot of special characters in Korean ready-made syllables but that takes a huge amount of time. It would be much easier if you could just enter the single letters and let the computer compose the syllable. Thank you, Best regards, Herman Meester Rotterdam, Netherlands
