You know, it’s funny how we’re often told to avoid the passive voice like the plague. Grammar checkers practically scream at you, and writing handbooks often give the same stern advice: “Use active voice!” But honestly, for most of us, especially those in fields like engineering, the whole active versus passive thing can feel a bit like a foreign language. What does it even mean?
Let’s break it down, shall we? Think of a simple sentence: “Acid etching removed the rust.” Here, “acid etching” is the actor, the one doing the removing. The verb is “removed,” and “rust” is what’s being acted upon. This is the active voice – the actor comes first, then the verb, then the receiver. It’s direct, it’s punchy.
Now, what happens when we flip that around? We get: “The rust was removed by acid etching.” Suddenly, the focus shifts. It’s no longer about the acid etching; it’s about the rust. The receiver is now at the front, followed by the verb (which now includes a form of 'to be' – 'was removed') and then the actor, often introduced by 'by'. This is the passive voice.
So, is it inherently bad? Not at all. In fact, sometimes it’s downright necessary, especially in technical writing. Imagine you’re documenting a process. You might write, “The pH was maintained at 6.8.” This implies that someone maintained it, but the focus is on the pH level itself, not on who did the maintaining. If you were to write, “I maintained the pH at 6.8,” it sounds a bit too personal, perhaps even a little boastful, in a scientific report. The passive voice allows us to step back and focus on the subject matter without getting bogged down in who did what.
It’s also about emphasis. If you’re writing about bees and their role in pollination, you’d naturally say, “Bees carry pollen” (active). But if your article is all about pollen, then “Pollen is carried by bees” (passive) makes perfect sense. It’s about choosing the right tool for the job, depending on what you want your reader to focus on.
Where things do get tricky, and frankly, a bit tedious, is when the passive voice gets distorted. This is where the verb gets hidden away, often turning into a noun. Take our earlier example, “The rust was removed by acid etching.” This is perfectly fine. But then you might see something like, “Removal of the rust was carried out by acid etching.” Suddenly, “was removed” has become “removal was carried out.” The verb is buried, and the sentence becomes clunky, pompous, and frankly, a chore to read. It’s like dressing up a simple idea in an unnecessarily elaborate costume.
This kind of “distorted passive” is a common pitfall in scientific and technical writing, making prose impenetrable. We become so accustomed to seeing it that we don’t even notice how awkward it sounds. Think about “Measurement of the resistance was carried out by the ohmmeter.” It’s so much cleaner to say, “The ohmmeter measured the resistance” or even, “Resistance was measured by the ohmmeter.” The distorted version adds nothing but wordiness and a sense of unnecessary formality.
The passive voice, when used thoughtfully, isn't a grammatical sin. It's a valuable tool that allows us to shift focus, maintain objectivity, and sometimes, just sound more natural in specific contexts. It’s not about avoiding it entirely, but understanding its nuances and knowing when it serves the story best, and when it just gets in the way.
