That’s how many comments are on a friend’s Facebook thread (so far) in response to his question today: Is it: a historic or an historic?
This is one of those quirks in the English language where you make your decision based on the sound of the letter in the context of the word rather than by the isolated letter itself.
My friend, Chris, who I went to high school with and worked in an Acme photo lab with (you know, in the late 80’s before anyone owned a digital camera and you had to drop off your photos to get printed), had heard a phrase on the news about the pope retiring being “a historic day” and he questioned if that was stated correctly.
My answer was yes, it was, but apparently my answer and about 75% of his other friends’ answers (including his wife’s) didn’t satisfy him, so I did a little research and pointed him to Judy Vorfeld’s post on the topic (after all, I had some book editing to do!) Here’s the link I gave him. http://editingandwritingservices.com/a-or-an-before-words-beginning-with-h/
If you speak/write American English, here is a safe rule: if the “h” at the beginning of the word is “hard” so you hear it (like in history), it is preceded by “a,” not “an.” If the “h” is silent (like in honor), it would be preceded by “an,” not “a.”
For example, “A historical memoir written by an honorable gentleman may contain a horrific story or two.”
