Yes, you can start a sentence with And

Following up my notes from last week, I thought I’d point this out.

However, this is a stylistic preference rather than a grammatical ‘rule’. If your teachers or your organization are inflexible about this issue, then you should respect their opinion, but ultimately, it’s just a point of view and you’re not being ungrammatical. If you want to defend your position, you can say that it’s particularly useful to start a sentence with these conjunctions if you’re aiming to create a dramatic or forceful effect.

This is one of my favorite things about language. It is constantly evolving. Constantly changing to meet our needs and our time and our ever evolving humanity. There’s are a reason we no longer speak in thous and shalts. Even my spell checker is flagging those two words. Why just this week I heard about a group of inner city kids using yo as an alternative to he/she…a much needed word in my opinion. Not sure about yo though. It makes me think of yo dawg. Yes, I’m dating myself. LOL

So if anyone gives you grief about starting a sentence with AND. you can tell them that I (and this dictionary) says hell yes you can!
