About amn’t I, aren’t I and am I not, of course there are no right or wrong answers about language in the sense in which there are right and wrong answers in Arithmetic. “Good English” is whatever educated people talk; so that what is good in one place or time would not be so in another. Amn’t I was good 50 years ago in the North of Ireland where I was brought up, but bad in Southern England. Aren’t I would have been hideously bad in Ireland but very good in England. And of course I just don’t know which (if either) is good in modern Florida. Don’t take any notice of teachers and textbooks in such matters. Nor of logic. It is good to say “more than one passenger was hurt,” although more than one equals at least two and therefore logically the verb ought to be plural were not singular was!
What really matters is:–
1. Always try to use the language so as to make quite clear what you mean and make sure your sentence couldn’t mean anything else.
2. Always prefer the plain direct word to the long, vague one. Don’t implement promises, but keep them.
3. Never use abstract nouns when concrete ones will do. If you mean “More people died” don’t say “Mortality rose.”
4. In writing. Don’t use adjectives which merely tell us how you want us to feel about the thing you are describing. I mean, instead of telling us a thing was “terrible,” describe it so that we’ll be terrified. Don’t say it was “delightful”; make us say “delightful” when we’ve read the description. You see, all those words (horrifying, wonderful, hideous, exquisite) are only like saying to your readers, “Please will you do my job for me.”
5. Don’t use words too big for the subject. Don’t say “infinitely” when you mean “very”; otherwise you’ll have no word left when you want to talk about something really infinite.
