Spelling, grammar and punctuation rules and consistency are fairly recent phenomena. I suppose, in general, they do help us understand each other. One of the problems is rules tend to change more slowly than language.
Michelle Pierce has an article at copyblogger called: Three Grammar Rules You Can (And Should) Break
I think she’s right. Each of the rules she pinpoints, when used, tend to make a sentence awkward and often interferes with understanding.
On the punctuation side, I’ve been known to tell students they only need three punctuation marks – periods, quotes and commas. If they want to get fancy, I suggest they add a semicolon for a total of four. My experience tells me these are really all you need to construct sentences that communicate clearly. Which is what we want, right?
What do you think? Do you have rules you ignore? Or do you follow them all. Either way, tell us what and why.
