Lighthouse Quiz

[Diane1954]

Q23 reads 'What is the only word in the English Language containing the first six letters of the alphabet A,B.C,D,E and F?'
but I can think of at least two words. Does it mean a six letter word or letters in order or what.?
Suggestions please

Certainly not a six-letter word - and it doesn't say letters in order. My first thought is 'feedback', but I guess that's one you've already come up with. No guarantee the question is right, of course!
