a grammar problem about "But, And,"

my teacher told me that don’t use “But, or And” to begin a sentence. Is it right? Thank you.

I AM WAITING, PLEASURE.

please

I think its right~

hi! i have the same problem !
In my poin, it’s right beace “But, And” use when connect some of sentences . that’s we can’t use to begin a sentence! we can use them to behind comma

The general rule is don’t begin a sentence with “but” or “and” unless you are very confident in your English skills. I found many examples in textbooks and articles where people begin sentences with “and.”

If you’re uncertain about how to use “and” or “but” to begin a sentence, you can use “However” instead of “but” and “In addition to” or “Also” instead of “and”.

Thank you all.

But or And is the continuation of something.  Offence is better than defence.  Start your own talk without merely replying.

thank you have describe a very suitable substitute :)

I never use "and" to begin a sentence.

Sentences should not be more than two lines of typewritten text. If it is and you have used and more than twice, you need to more than one sentence. Also a sentence is supposed to express a complete thought.

You can use "but" to begin a sentence but I tend to use however.

In business writing it is usually better to just state your stance without a lot of ifs ands or buts.
