The second "N" in Historian

I was reading an article in the Economist today (check me out!) about the life of a famous American historian and liberal who was close to the Kennedy administration. An interesting read to be fair, actually it was an obituary now I come to think of it, which is neither here nor there, but one thing struck me as I was reading. Fortunately it was a figurative strike, and not a literal one. As with most newspaper articles there were little subheadings throughout the article, and one in particular caught my attention - An Historian in Love. Now, being a bit of a stickler for grammar myself I obviously found no fault with the use of "An", it is grammatically correct. But, and this may sound a bit strange, but is it a bit too correct? What I mean is that we are all taught to use "An" before a noun beginning with a vowel, which is all fine and dandy, and then we are told to use it before nouns beginning with a "H" too for reasons best known to someone who cares. I never really thought about it before, but I happened to say this little subtitle out loud to see how it rolled off the tongue, and frankly it didn't. Try it now, "An Historian in Love". Now try it without the n, "A Historian in Love", now I admit it sounds a little unusual at first, but it seems to roll far easier in my opinion. That then got me to thinking about our use of "whom", and I remembered once being told that my use of "whom" in a piece of work, although correct, was almost too correct and a little bit pretentious. Now, fortunately I didn't reply "pretentious, moi?!" and merely erased the offending "m". Language changes constantly, I know this as well as anyone, and in many cases the changes are for the better, so maybe it is time to drop the n in front of nouns beginning with a, or indeed, an H. What do you think?
That said, not all changes in language usage are for the good. I was walking past a large office block the other day and I saw a sign in the window that caught my attention "Jobs available init".
Now, although hardly proficient in the current language of the street, I am aware of the over usage of the word "init" at the end of sentences, particularly among the disaffected, working classes and other people who shouldn't be allowed to vote. So, being an upstanding citizen and a great believer in people talking proper, I took it upon myself to highlight this aberration to the company receptionist. It didn't go too well. Before I had even found my stride in explaining the complexities and vagaries of the English language the aforementioned receptionist popped a chewing gum bubble, tapped a well chewed HB on the desk and informed me that the sign actually advertised positions currently available in the I.T department. Needless to say I beat a hasty retreat.

Obviously, that didn't actually happen and was added merely for comedic effect. Honest.

Until next we meet.
