The ear is the only true writer and only true reader
Read your writing out loud.
You should write for the ear rather than the eye. An excerpt from Week 1 of ENGL 450 Daily Themes:
The ear does it. The ear is the only true writer and the only true reader. I have known people who could read without hearing the sentence sounds and they were the fastest readers. Eye readers we call them. They can get the meaning by glances. But they are bad readers because they miss the best part of what a good writer puts into his work.
In contrast, the eye is a barbarian. Because of this, you should write for the ear rather than the eye.
