Inalienable vs Unalienable: Meaning, Difference, and Usage

The short answer is this: inalienable is the more common and preferred word, while unalienable is also correct but less widely used.

I remember reading the phrase “unalienable rights” in an old text and then seeing “inalienable rights” everywhere else. 

That made me stop and think: Are these two different words, or is one wrong? Like many readers and writers, I searched “inalienable or unalienable” to clear the confusion. 

The mix-up happens because both words look correct, sound formal, and appear in legal or historical writing. Once I understood their origins and usage, the confusion disappeared. 

In this article, I’ll explain everything clearly and simply, so you can choose the right word with confidence.

The Origin of Inalienable or Unalienable

The story behind these words explains why both exist.

Both words come from the Latin alienare, meaning to transfer or give away. The idea is simple: if something is alienable, it can be transferred. If it is not alienable, it cannot be taken away.

• Inalienable uses the Latin-based prefix in-, meaning not.
• Unalienable uses the Germanic prefix un-, also meaning not.

Historically, unalienable appeared earlier in English. Over time, inalienable became more popular, especially in legal, philosophical, and academic writing.

That’s why both are correct, but one clearly dominates modern usage.
