The word challenge is difficult to spell for those of us who are poor spellers.  I know this so well. This week when I was on the road doing training in Western Pennsylvania, I was trying to spell the word challenge.  Without the electronic speaking dictionary or a computer with spell check, I was stuck.  I resolved to find a mnemonic clue to remember how to spell the word challenge once and for all since this is not the first time I have found myself frustrated by the spelling of this word.  When I analyze why I cannot spell the word challenge, there is no apparent reason.    I can recognize it when reading, and when I am looking at it, I cannot imagine how I spell it incorrectly.  But these are the various ways that I have spelled to word:  challange, challene, challege, challennge and, yes, occasionally I do spell it correctly.
