Jobs sometimes become tedious and boring when every day is the same, and that is also true with reading. When the writing offers no variation in sentence length, the repetition is monotonous.

The simplest of sentence structures is tolerable in a children’s story: This is an elephant. It is a very big animal. It has a long nose called a trunk. But you can make professional writing more lively and more effective by using particular techniques, one of which is varying the length.

Consider this quote from publisher Malcom Forbes:

Somebody has said that words are like inflated money:  the more of them that you use, the less each one of them is worth. Right on. Go through your entire letter just as many times as it takes.  Search out and annihilate all unnecessary words and sentences. Even entire paragraphs.

After a 24-word opening sentence, he follows with a two-word expression. Then he stretches out with a longer sentence and ends with a three-word fragment. The contrast provides a pleasant quality to the reading. Short incomplete thoughts (fragments) are acceptable when they help to create a natural, conversational tone, even in business communication.

Experiment with your writing. The subject-verb-object structure is at the core of clear writing, but break the pattern periodically. Varied structures are more enjoyable to read, and they often reinforce the meaning of your paragraph.
