Are there any words in English which start with the letter Q, but the second letter is not U?

I agree with Ms. Susan Marx. Yes, there are words starting with letter Q without letter U immediately after it, but those words are of Arabic or Greek origin. Following is a list of such words:

1. Qwerty/s – the name for a keyboard whose letters are in the standard typewriter arrangement (hence, Q, W, E, R, T, Y in the upper left-hand corner of the letter section).

2. Qi/s – an alternate spelling of “chi.” Much like chi is the vital energy circulating through the body, “qi” is vital to your WWF arsenal.

3. Qat/s – an alternate spelling of “khat,” which is a white-flowering evergreen shrub found in Africa and the Arab Peninsula. Apparently chewing it is kinda fun – it contains cathinone which is a mild stimulant.

4. Qaid/s – an alternate spelling of “caid,” which is a word for a local governor or leader used most commonly in North Africa and the Muslim state of Al-Andalus (also known as “Moorish Spain”) which existed from.

5. Qoph/s – an alternate spelling of “koph,” (alternate spellings are totally trending right now) which is theth letter of the Hebrew alphabet.

6. Qanat/s – an underground tunnel for irrigation used mostly in hot, arid climates.Surprise! There are alternate spellings for this one, too — including kanat, khanat, kunut, kona, konait, ghanat, and ghundat, none of which are accepted in WWF.

Great day!

Well, Qatar is a starter, and qi ('chi', or Chinese way of life), and qat, and qadi. You will be very interested and surprised to know that QAT (evegreen shrub from Arabia and Africa) and QADI (religious muslim judge), and few other words have Arabic origins! 

Most of this, I have learned as a scrabble player. So, copying from twl06 (true word list) of scrabble at word-grabber.com, here are the words:

Enjoy learning!

Yes there are such words though not many; for example modern English coinages: qwerty and qiana, or company names like Qantas.  

Not of English origin only - like Qatar, Qoran
