TECHNICAL WRITING TIPSCopyright 2004 Lori Jo Oswald, Ph.D. of Wordsworth Writing, Editing, and Document Formatting ServicesActive and Passive Voice “Don’t use passive voice,” is probably one of those red-ink English teacher comments you sometimes saw but that was never explained. Active voice is preferred because it is easier to read and to understand, so it is especially important in technical material. Basically, in the active voice, the subject comes first. Another way to look at it is that the subject does the acting.

• ACTIVE: The contractor evaluated the data.

In passive voice, the subject is acted upon. The reason this is a problem is because it is wordy and harder to follow.

• PASSIVE: The data were evaluated by the contractor.

Be SpecificTechnical writers should be as clear and specific as possible, avoiding vague language. Therefore, if you are seeing words like “many, some, a few” in a document, it probably needs revising. Instead of writing “a very high concentration,” for example, give the exact measurement. Give the depth of a test pit rather than just calling it “shallow” or “deep.” Instead of merely saying something is “contaminated,” provide the reader with the amount by which the standard is exceeded and specifically name the compounds involved. Instead of saying something is satisfactory, state exactly which standards or regulations it meets.
ClichesAvoid cliches like the plague; they are overused expressions that have lost their meaning. Even if you are blind as a bat, you can see a clich
