Hi Sasquatch!
Mind if I call you ‘Squatch’ for short?
I will for this post, but, if you hate it, I won’t ever again.
So far, I agree with pretty much everything posted so far. I have always found the best remedy for atrocious grammar and syntax is reading. As you read more, Squatch, you’ll find yourself developing a ‘feel’ for grammar.
Things start to feel right right when they’re right and odd when they aren’t. You can’t always tell why it feels strange, but, something inside you stands up indignantly and pokes the part of your brain that decides when you’re comfortable.
That, my dear Squatch, is the analytical part of your brain comparing the words you see now with all memories of similar situations. If you have read something before that is similar to what you are reading/writing now, you will have a feeling about it now.
Now, this doesn’t always happen. It only happens when you see something you’ve seen before. You have to have an adequate level of prior experience with that particular word, phrasing, context, etc. for your memory to be a reliable resource. The more accurate your understanding, the less comfortable you feel reading something that has been phrased incorrectly.
The next most helpful thing, in my experience, is asking for criticism. So, Squatch, good call in asking for advice!
