Qatar - as in the airline has no 'q', but it is not an English word, so may not count, although you did not specify that the word has to be English in origin.
We could just use the letter KW so we would have Kween, Kwick, Kwango, Ekwator. That looks weird doesn't it - I guess that's why we have QU.
Does qwertyuiop count?
No apologies Bob, sorry, they are all still foreign words, it even says they are from other countries!! I think QWERTY is the nearest so far but even that is cheating as it is only made up from the order of letters on a keyboard!!
Wow The Prophet , I had no idea though I must say I have wondered about that . I really suppose I should have known but at least I do now , thankyou. :-) x
This is the first line off that page Bob: While this is true in the vast majority of cases, there are some exceptions, the majority of which are naturalised from Arabic, Chinese, Hebrew, Inuktitut, or other languages which do not use the English alphabet
