"Exercise" stumped me for the longest time. Now I get it.
"misspelling" - two s's or one?
"self-awareness" (or any word with "self" that comes before it) - one word? one hyphenated word? two words?
"Gemutlichkiet," obviously. MUCH easier to spell free beer Fridays.
My last name - took 3 months to learn to spell. My brother David reminds me that it can be spelled to the Mickey Mouse song. "S - T - I - E - G - E -" (are you singing it yet?) "M - E - Y - E - R"
Oh, it seems like there are so many more. But it's a Friday night, and I'm brain dead. What words do you find a challenge?
