Compare them:

Only the first two letters differ.
They Mean the Same Thing
Unlike many word pairs that have different meanings, these words are near-perfect synonyms.

Historical Usage Creates Additional Confusion
Many people first encounter unalienable in the famous phrase:
“Life, Liberty and the pursuit of Happiness.”
The phrase refers to unalienable Rights in the United States Declaration of Independence.
Because this document is so influential, some people assume unalienable is the standard spelling everywhere.
In reality, modern English usually favors inalienable.
The Historical Background of Unalienable and Inalienable
The history of these words explains why both exist.
Both derive from the verb alienate, which originally meant:
- to transfer ownership
- to give away property
- to remove possession
When a right is alienable, it can be transferred.
When a right is inalienable or unalienable, it cannot be transferred.
The Declaration of Independence
One reason unalienable remains famous is its appearance in the U.S. Declaration of Independence:
“…endowed by their Creator with certain unalienable Rights…”
This historical usage has preserved the word in American political and legal discussions.
