One of those mornings (at the day job) when I’m wrapped up in my work and keen to write more. There’s a faintly anachronistic discussion about whether or not conjunctions may be used to start a sentence, but it’s nice to be working somewhere that considers such things, I’m thinking, as I walk to the market to buy lunch. And yeah, there was a time when received wisdom ruled this to be one of many things you ‘couldn’t’ do, which you knew people did do, really. But that was way back before the accepted usage argument gained credence….
“Authorities do not all agree on the status of sentences that start with coordinating conjunctions. Some  consider these to be grammatically incorrect. Others consider it an issue of style.”
