I find nothing wrong, in grammar, in using the word "among" as the first word in the sentence.
As in: "Among those who live in the Philippines, the largest religion is Catholic".
Those, on this forum, who know better than I, may disagree ---- and, if they do, please correct me.
Otherwise, I stand on what I say.
Capitalization
If it is the beginning of the sentence, it needs a capitol. If not, then just leave it blank. Only if it's either at the beginning of a sentence or a proper noun.
At the beginning of a sentence. When using a proper noun
You use a capital letter when a word is:A proper noun. Example, "My name is Tony."In the beginning of a sentence. Example, "Tony likes playing."
At the beginning of a sentence and when it forms part of the proper noun. Example: IBM Annual Report
yes, for example: I wanted to wear my green pants, but i didn't have a shirt to match. you aren't supposed to use but at the beginning of a sentence, though. it's not proper grammar.
Sure, I can use "so" at the beginning of a sentence.
No, except at the beginning of a sentence because it is n ot a proper n ou n.
Yes, starting a sentence with "then" is grammatically correct, especially when showing a sequence of events or actions. However, it is usually used sparingly to avoid overuse and maintain variety in sentence structure.
