Inexplicable vs. unexplainable

Inexplicable and unexplainable are mostly interchangeable—both describe things that can’t be explained—and using one in place of the other is never a serious error. They have differentiated slightly in modern use, though. Inexplicable tends to describe things that are seemingly without logic, especially human actions, feelings, and creations, but also other things that one can’t explain in rational terms. Unexplainable tends to describe nonhuman things, especially natural and supernatural phenomena, and it is also used for human things that are difficult to explain but not necessarily irrational.

In other words, while inexplicable things have seemingly no logic to them, unexplainable things are just very difficult to explain. In fact, unexplainable could often be replaced with unexplained with little loss of meaning.

This differentiation is new, however, and not deeply engrained in the language—it is much in evidence in recent news and blog writing but less apparent in recently published books—so it will be interesting to see whether the words continue to grow apart in the coming years.

Examples

It was an extraordinarily good year for odd, inexplicable and idiotic behavior. [Wall Street Journal]

[O]n Sunday we lost Sir Patrick Moore, an astronomer who explained more unexplainable things to more lesser-educated people than Brian “photogenic” Cox could in a month of Tuesdays. [Independent]

[B]ut conspiracy theories can help explain the unexplainable, even when outlandish. [Daily Beast]

Don’t overgeneralize. Don’t stigmatize in a rush to explain inexplicable evil. [National Journal]

But less impressive were the long and inexplicable off-stage breaks, which had punters in the bleachers audibly shouting. [Sydney Morning Herald]

But some events are unexplainable — suggesting that what happened was not from a scent, but a sense. A kind of “sixth sense.” [Omaha World-Herald]

Comments

  1. Thanks for the explanation but you lost credibility when you used “evidenced” (…”it is strongly evidenced in recent news…”) incorrectly. The word you were looking for is “evinced”. “Evidenced” is generally reserved for legal usage. With that said, it is widely misused.

  2. janners11 says:

    The OED has “evidenced” meaning “demonstrated, proven” dating to the 17th c. … I don’t love the word but I don’t agree that it was incorrect. OTOH, I’m not persuaded that your examples evidence, evince, or demonstrate the distinction you’re trying to make. I’ll have to keep an eye on “inexplicable,” I guess. — Jan Freeman
