Okay, there’s no rule that says senetences can’t end in prespositions. According to my Gregg Reference Manual (9th edition), “Ending a sentence with a prepostion is not incorrect. Wheteher or not you do so should depend on the emphasis and effect you want to achieve.” All of the usage guides I’ve read agree with this opinion.
Infinitives may be split. Gregg reference manual, Section 1046.
And why can’t I start a sentence with a conjunction?
These “rules” can and should be broken when necessary. However, I try to avoid doing so in formal writing because people without the proper training may misconstrue the usage as being incorrect.
And here’s another one. You don’t need two spaces after a period. With desk-top publishing, one space works just fine. The US Government Printing Office and the Chicago Manual of Style both agree.
I agree that language is flexible and constantly evolving. However, communication that is clear and precise helps reduce the risk of misunderstanding.
Just a few examples:
“This offer is not available in all areas.” (Commonly used in adverstising disclaimers in the States.) What does this mean? It’s not available in ANY area, or it’s not available in SOME areas?
Danglers:
“Lying deep inside the large colon, the physician noticed a grade 3 tumor.” What this sentence is supposed to mean is that the doc saw a tumor deep inside the colon. What it actually says is that the physician saw a tumor while he or she was lying deep inside the [patient’s] colon. An uncomfortable situation for both parties, I’d imagine. Or a more sublte example: “Based on my information, this candidate is in an excellent position to win the election.” Does this mean that my information will help the candidate win, or, more probably, that I have information suggesting that the candidate has a good shot at winning? The fact is that the canidate is not based on my information.
There are dozens of other examples of poor grammar and usage practices that (notice “that”, not “which”) can make your meaning imprecise. I brought up these merely to illustrate the point that, while many supposed grammar rules are antiquated or not useful, clarity is still critical for effectice communication. Once you understand the way the language works, clear communication is more about logic than remembering rules. I also brought up these points because the message boards have been sort of slow lately, and, well, I was bored.
