Let me introduce my question with a quote from Tarbell:
" To express yourself effectively, words are important. Study your language well and its proper use. Imagine if Thurston had come out on the stage and said "Dese, dem and dose". People expect a magician to be to be educated in the magic of words and phraseology as well as his mysteries."
I studied English as a foreign language, many years ago, and feel I am no longer improving. Worse, my level of expression is deteriorating, since I no longer live in your country. I had to write a short piece recently and was surprised by the amount of grammatical errors I made. I was also disappointed by the heaviness of my writing. It seems my inner voice needs a lot of work and polishing.
I decided to remedy this, and I thought I would ask for advice on this board, since many of you are either used to speak in public, or make a living from writing.
My current line of thought is this: go and study Grammar, Logic and Rhetorics, and at the same time take some public speaking classes. I'm lucky to have a Toastmaster's club next door to me, so that's one down, three to go.
For the rest, I'm looking for good, solid references. I've just bought "Classical Rhetorics for the Modern student" (Corbett&Connors), and "Introduction to Logic" (Gensler). They seem to be "industry standard"?
But I don't know where to start with Grammar. The basic grammar books for foreigners are too simple, and at the other "technical " end of the spectrum, much too obscure.
What is the grammatical bible for English writers? Which book do you use in creative / technical writing classes in university? Could you recommend a reference with lessons and exercises?
This doesn't address style at all, should I assume that this is one thing that you either have or you don't?
