Usage Notes

What's the Difference Between 'Historic' and 'Historical'?

And should you use 'a' or 'an' before each one?

Historic and historical: what a pair. First off, there's the question of whether to use a or an before them. Both a and an are used, but a is far more common—as much as four times more common in American English, by some measurements—which is what you'd expect for a word that, like habit and hero, begins with an audible \h\.


At their core, 'historic' and 'historical' are simply variants of the same word. However, over 400+ years of use, they've mostly settled into distinct roles.

So why do some people say "an historic" and "an historical"? Well, historic and historical differ from habit and hero in a crucial way. They have their accented, or stressed, syllable second, not first. It used to be that an initial "h" was not pronounced in many such words, which is how "an historic" and "an historical" came to be used in the first place. Both words are now, however, typically pronounced with an audible \h\. (A vs. an can be tricky: in fact, we've written an entire article about it.)

As for which word to use where, the answer is similarly complicated.

The two words are at their core simply variants, but over 400-plus years of use, they've mostly settled (emphasis on "mostly") into distinct roles. Historical is the typical choice for the broad and general uses relating to history. It's the one used to modify words like museum and society, and it's the one found in contexts like these:

People who write about matters such as these tend to pretend that the differentiation is more absolute than it is; there are, in fact, instances to be found in which skilled writers apply one word where the other is typically found, and vice versa. Still, the distinction outlined above is a good one to follow if you want to communicate efficiently with your reader.
