Sir, Whether the European Central Bank chooses to embark on a programme of sovereign QE (or quantitative easing, as it used to be known) is of little day-to-day interest to most citizens of the EU. Whether the compilers of dictionaries accept that QE is now a word in its own right — as opposed to an abbreviation — is of far more relevance to us scrabble players. Using a Q without needing a free U it would rapidly be up there with Qi (the Chinese word for life force) as one of the most useful words in the lexicon.

I would think that for the foreseeable future QE would be ruled an abbreviation, not a word, although enough years of macroeconomic misery eventually could flip this the other way.
