English is my native language and, as such, I have a poor understanding of its construction. I know when I learnt French, we were taught about the basics of sentence construction and the various components thereof but I can't remember that in English (maybe I was too young? Not sure).
A couple of recent threads have highlighted my woeful lack of knowledge about the various aspects of verbs/tenses/etc and their use in sentence construction and the affect that sentences have on the reader. It made me wonder how essential it is to know these things to be a good fiction writer. Is it imperative that we know how to form the perfect sentence or is it enough to 'just know it's wrong/right'? Surely we need to know the basics so we can identify what is/isn't working in a sentence and need the tools to fix it if required?
There's mixed opinions on whether having formal education on these matters is useful or not, I'd be interested in what others have to say on this. I read some posts on threads and it's like they've been written in a foreign language! I try to read up on things I don't know but even a basic tuition can be over my head!
I'm not picking on you here but will point out that having opened your thread with a sentence in which you told us that you learnt rather than learned speaks to your readers.
I hated English (the taught subject, not the language) in school. I have never been one to be able to hold a strong discussion about adverbs, nouns, pronouns, adjectives, participles, verbs, etc. It literally bores me to tears.
Now that is not to say that I do not understand the language. I love English and in fact languages themselves fascinate me. I speak only 5 languages currently, and while I can read in all five, I am not well written in two of the three in which I can also write.
I am learning a sixth language slowly as well. But as far as writing goes, I may not be able to diagram a sentence or get the structure correctly identified, however I still know what the rules are. I understand some basics of punctuation, and the grammar and structure needed to compose a sentence.
I have been praised repetitively for my writing skills and style and this is not an "I'm so great" discussion. Rather it's to make the point that if you have a feel for writing, and can practice the basics, are willing to improve, and open to criticism (and I have had plenty of times where much more talented writers and kindly English teachers and professors have taken pity on me and have helped or attempted to help me) then strictly speaking it is not absolutely imperative that you know every detail of the craft.
I think that the fact that you are here and asking the questions is more important than not yet knowing all the answers. Its an opportunity for growth.
I would say that there are plenty of programs that will help you with sentence structure, spelling, tense, passive or active voice, grammar, etc in the editing and correction phase of your writing.
Microsoft Word for example.
Having a good vocabulary helps a lot. One of my friends suggests reading a few pages of the dictionary every day as a vocabulary builder.
Best wishes to you with your writing. Cheers!
