Sorry, but there is no concrete answer to this question. I can’t just tell you that you’re only allowed to write the word “the” once every fifty words. Ahem. No. Writing doesn’t work like that. There is no definite answer.
However, what you should NOT do is write, “The train went by. The dog barked. The cat meowed. The. The. The. The.” That would be a little overboard….But the same goes for all words; you wouldn’t want to start every sentence any single word. “A train went by. A dog barked. A cat meowed. A. A. A.” It sounds just as bad.
The trick, I suppose, is to just make sure that you don’t keep on repeating yourself. Repetition anywhere—whether it be a single word or an entire phrase—is a bad idea. If you’d like, you could visit this page on my blog….It gives tips on how to make your writing sound better.
