Anyway.
You can use however instead.
You can just about use any word possible to start a sentence
use the word job
yes it depends on the sentence.
On the other hand,
The expression, " As for myself, I ... " also, " In my opinion ...", " I believe ...."
No, You cannot use but to start a sentence.
That word is badly out-of-date. I recommend you use amend instead.
whats the answer
No
Yep. There's no problem with using 'an' anywhere you want to. You shouldn't use and at the start of a sentence, though.
A sentence for the word peculiarity is: That boy does have one peculiarity, he puts his money in his sock instead of in his pocket. And that my friends is how you use the word peculiarity in a sentence.
