No, it's not wrong. A sentence can begin with 'as', for example:
As always, Jack is the first one in the office this morning.
As I walked in, he had already made the coffee.
As coffee goes, it's really strong.
As long as you're here, have some coffee.
The word 'is' can begin a sentence but not be a question when it is the subject of the question. Example sentence - Is can be the subject in a sentence. But only in sentences of that type (above) or, 'Is' is a two letter word. Otherwise is cannot begin a sentence.
Yes. There is no word that cannot begin an English sentence.
It is possible to have a sentence with the word it at the beginning, as this sentence proves.
The answer I gave was wrong.
yes you can
Never
Of course you can. There is no word in English that cannot begin a sentence.
Yes, you can begin a sentence with the word "or" when presenting options or alternatives. For example, "Or you can choose to study abroad for a semester."
Yes, a sentence is allowed to begin with the word "with". For example: With all the pressure of high school people were becoming stressed.
I'm not sure why you wouldn't begin a sentence with it. It's just a word. All of those grammar rules they taught in school are wrong anyway. You can start any sentence with any word; you just have to follow the rules for starting the sentence that way. Why? Because if you didn't follow the rules, then you would end up with a bad sentence! You're perfectly allowed to put 'you're' at the start of a sentence in any case.
this is wrong
lettuce begin (let us begin)
