Noticed this tweet the other day from our abundantly anglophone Mayor, Antonio Villaraigosa:
Looking forward to an Historic Inauguration Day...
Really? Our Mayor wrote that?
Here's a good discussion on that affected construction:
Perish the thought that our Mayor might have it both ways.
The stylebook of the London Times calls for an hotel, an historic and an heroic. But, remember, that's British English.
H.W. Fowler (writing in British English and, near as I can tell, about the same time as Baker) says an was "formerly usual before an accented syllable beginning with h," citing an historian, an hotel, an hysterical scene, an hereditary title and an habitual offender. He continues: "But now that the h in such words is pronounced the distinction has become anomalous and will no doubt disappear in time. Meantime speakers who like to say an should not try to have it both ways by aspirating the h."
