Maybe this is better:
About September 20 the foliage begins to turn.
Some people don't like starting a sentence with a preposition so you could say:
The foliage begins to turn about September 20.
No, the correct grammar would be: "Around September 20 is when the foliage begins to turn."
Example sentence - Our school begins classes in September.
"When" is an adverb when it begins a sentence.
No. Not unless the sentence begins with friends.
The correct grammar is "a Hawaiian luau" because the word "Hawaiian" begins with a consonant sound, so it should be preceded by the article "a".
'Until the class begins' is not a complete sentence, and therefore it can not be classified. It is a clause, introduced by the conjunction 'until.' 'Until the class begins' is not a complete thought. We're still waiting for the rest of the sentence. Something will or will not happen, take place, be allowed, etc., 'until the class begins.' Without that something being stated, there is not a complete thought. It takes a complete thought to make a sentence. 'The class begins' is a complete sentence. It sounds like an announcement of some kind. It is perhaps a little awkward or stilted, but it is a complete sentence. It expresses a complete thought. Furthermore, it is a declarative sentence. It states a fact.
that is correct grammar
Example sentence - Our school begins classes in September.
Im not sure, but I do not think there is unless people do not have proper grammar...
Spring begins on March 21 in the northern hemisphere, but on September 21 in the southern hemisphere.
There is no such thing as the September axis.
In formal writing you would not begin a sentence with because, therefore, the kind of sentence that begins with because is informal.
No. Not unless the sentence begins with friends.
