Q is for...

Quantitative Easing.

No I am not really going to talk about quantitative easing, I am not qualified to do so. I could easily quote some experts but there's a risk it wouldn't be quite right so I think I will just stay quiet on the matter.

Q in Scrabble is worth 10 points, and if you play it with the letter 'I' it makes Qi which is the term for the 'Chinese life-force', It's a legitimate play and can make or break a game.

Q Magazine was originally going to be called 'Cue', as in 'to cue a record to play', but, apparently they (being Mark Ellen and David Hepworth (thanks Wikipedia)) thought people might think it was a snooker magazine, so changed it to the far more emblematic Q - and ruined John Virgo's dream of releasing a snooker magazine called Cue in the process.

Q is a troublesome, yet highly interesting, letter and almost all the words it begins with catch your eye in among a sentence of other more humdrum vowels and consonants.

For hardcore Scrabble fans out there, Qaid is a legitimate word too, meaning A Muslim tribal chief, judge or senior official. So there you go. No need to wait for that elusive U to show his horse-shoe form in order to play the killer Q.
