There’s a time and a place for everything, naturally, and while I love to talk about flouting stupid rules, most of the rules are actually good advice that’s just a bit . . . misapplied. As Mr Knightley says:
Better be without sense than misapply it as you do.
Right! So, let us understand the so-called rules so that we can apply them correctly, shall we?
Avoid passive voice
This is almost always good advice. Generally speaking, passive voice is awkward. Naturally, there are exceptions to that—sometimes rephrasing the passive into active voice is even more awkward, sometimes we have to conceal the actor, sometimes it’s just not important.
Avoid the past progressive
In general, the past progressive form (was [verb]ing) isn’t the strongest. (How’s that for diplomacy?) There are a few specific reasons to use it—mostly to show an ongoing or interrupted action in the past. Overusing it, though, results in flabby writing.
Avoid the verb “to be”
It’s true that sometimes the verb “to be” can be used to make such evils as the passive voice, the past progressive, and really boring, flat writing. Compare, too:
The stockings were hung by the chimney.
The stockings hung by the chimney.
The first one is passive voice (and The Night Before Christmas, yes?), longer and takes the oomph out a verb. (‘Hang’ isn’t very oomphy in the first place, so let’s try to help it out, eh?)
However, again, “to be” is an important verb that you don’t want to completely excise from your writing—or it’s gonna get really weird.
What other rules do we see that are pretty good advice?
