For people of a certain age, their English teachers would be in a cold fury as soon as they read the headline to this blog. The title starts with 'and'. Why? Because - see I've done it again - these are the words which help keep people reading your social media, blog or website content.
So - and that's the hat-trick - the old rules of grammar no longer apply - if they ever did. Of course, you won't overuse this device. But - that's a four-ball - where you are continuing with a previous thought, then this use of 'joining' words makes simple sense.
And it's also okay to finish a sentence a preposition with!
REMINDER: It's okay to want to follow the traditional rules of grammar - but not where they get in the way of gaining customers!
