Unalienable vs. Inalienable – What’s the Difference?

As historical documents go, the United States Declaration of Independence is fairly accessible. It is written in a language that is still widely spoken (unlike many texts in Latin and Classical Greek) and, at less than 300 years old, it is still relevant to modern events.

One word may cause some readers to pause, though. The word unalienable (as in unalienable rights) may seem out of place to modern speakers. Isn’t the word inalienable? How could a typo slip into such an important document?

As you can see, unalienable dominated during the time Thomas Jefferson wrote the Declaration of Independence. Since the 1830s, however, most writers use inalienable outside of direct quotations from the Declaration.

As Bryan Garner states in his book Garner’s Modern English Usage,

  • [Inalienable] is slightly better formed, with a Latinate prefix as well as suffix…inalienable is preferable in all context except those where the Declaration of Independence is directly quoted or cited.

Trick to Remember the Difference

Today, inalienable is the preferred spelling of this word. The prefix in- is a Latin negation, while un- is an English form. Inalienable is therefore closer to the word’s roots in Latin.

Unalienable is appropriate when quoting the Declaration of Independence, but inalienable is a better choice in most other contexts. Since the prefix in- forms the last two letters of the word Latin, and inalienable comes from Latin, it’s easy to remember which version of the word to use.
