That one difficult word…

You know what it is.  Everyone has one, although every person’s word is different. (You may have more than one; many people I know do.)

The word we’re talking about?  It’s the one that you always have trouble spelling, no matter how often you write it.

My word is dilemma.  I can’t ever remember if the I or the E comes first.  It’s pronounced DAH limma, so shouldn’t it be spelled DELIMMA?  Nope, the I comes first.  Weird.

What’s your word?
