Today’s word is… ‘interrobang‘.
I found it in this fine article about nelogisms and the silliness of overly-rigid definitions of what is and is not a ‘real’ word, written by lexiconographer Erin McKean. It was described over at Boing Boing as being about ‘English as a user-modifiable technology’, which is a lovely concept… though not one explicated in the original article.
Oh… and interrobang means ‘a combination of the exclamation point and the question mark’. The title of this post, if you haven’t already got the joke, refers to this piece by Aleister Crowley.
