There's only one way to spell Hanukkah. Unfortunately, it's in Hebrew. When translated to English, the word becomes trickier to express. There's actually no way to spell the guttural "hecht" sound used in the traditional Hebrew pronunciation; Ch and H are the closest we can get. And then there's the issue with the double k's, seemingly added to give the final syllable a little more oomph. The phrase can be spelled Hanukkah, Chanukah, Chanukkah or Hanukah. Or you could go the easy route and look it up.
