yes specially if the sentence is an interrogative sentence. for example "From where does this package came from".
You can just about use any word possible to start a sentence
You can start a sentence with "Also"
No, You cannot use but to start a sentence.
Yep. There's no problem with using 'an' anywhere you want to. You shouldn't use and at the start of a sentence, though.
no
That cannot be done.
A capital letter.
Well that is a tricky question but i would say at the start of a sentence people would often use "I" at a start of sentence. There is loads of words to start a sentence so i can't tell you all of them obviously. example: "I" went to the shops to buy sweets.
the rain doesn't start until the night.
I would like to start with a startling revelation.
use it at the start of the sentence e.g "rest assured, my deed will be done"
uhhhmmm...well, you start off with a capital letter to start your sentence, then you have to put BEWILDERMENT somewhere inside that sentence, and of course you have to make it sound reasonable.and that's how you use bewilderment in a sentence.(:
