A while ago - in fact, a few years ago - I saw this and wondered, 'Being selling? - hmm':
It occurred to me that this 'being' might be a typo for 'begins'. Still, I thought 'being selling' made sense to me (if not appropriate in the given context).
When I saw the headline "Touro College accused of being selling grades and degrees", I was more confident that this was an instance of nonfinite progressive BE. But then, when I follow the link to the original article, the interesting construction is nowhere to be found.
I don't know about you, but I happen to think that being doing something, as opposed to doing something, is a wonderful stretch of the English verbal system. Why don't people do this more often?
Over three decades ago, Halliday spoke of this as a gap to be filled (in 'On Being Teaching', which you can see cited here). My question is, is the gap being filled now? Or would I be accused of being filling the gap too forcefully?
