What Does Revocable Mean?

Revocable is an adjective that means something can be revoked. To revoke something means to officially cancel, withdraw, or take back permission, authority, or a decision.

In simple English, revocable means changeable or cancelable, depending on the context.

Revocable in legal English

In legal writing, revocable often describes an arrangement that can be canceled or changed under specific conditions.

For example:

A revocable trust can generally be amended or revoked by the person who created it.

This is a common use in estate planning. However, the trust’s terms and applicable law determine what changes are allowed.

Revocable does not mean unlimited freedom

A revocable arrangement is not necessarily changeable at any time by anyone.

For example:

• A permission may be revocable by the person who gave it.

Irrevocable in legal English

Therefore, avoid treating the word as a guarantee that no legal change is ever possible.

The Origin of Revocable or Irrevocable

Revocable and irrevocable are related words. Both come from the Latin root connected with calling something back.

The origin of revoke

The verb revoke comes from Latin revocare, meaning “to call back.”

It developed into the English word revoke, which means to officially cancel, withdraw, or take back something.

For example:

The authority revoked his license.

This means the authority officially canceled his license.

The origin of revocable

People form “revocable” by adding the suffix “-able” to “revoke.”

The suffix -able means capable of being.

So:

Revoke + able = Revocable

The word describes something you can revoke.

The origin of irrevocable

Irrevocable adds the negative prefix ir- to revocable.

The prefix ir- means not in this word.

So:

Ir- + revocable = Irrevocable

The word describes something you cannot revoke.

Why do the words have opposite meanings?

The prefix changes the meaning.

This pattern can help you understand other English words, too.

Examples:

• Reversible / irreversible
• Responsible / irresponsible
• Regular / irregular

British English vs American English

British and American English use the same spelling for revocable and irrevocable.

There is no common British spelling change such as adding an extra letter to either word.

Pronunciation differences

Both varieties commonly pronounce revocable as /ˈrɛvəkəbəl/ and irrevocable as /ɪˈrɛvəkəbəl/.

Accent differences may affect the exact sound, but the spellings and basic meanings remain the same.

Legal writing differences

Legal terminology can vary by jurisdiction. The words themselves are standard in both British and American English, but the rules surrounding trusts, contracts, consent, and other legal arrangements may differ.

For legal documents, always follow the relevant jurisdiction and the wording of the applicable law.

Which spelling should you use?

Use revocable when you can revoke something.

Use irrevocable when you generally cannot revoke something.

The correct choice is based on meaning, not on if you are writing in British or American English.

Which Version Should You Use?

The best word depends on what you want to communicate.

United States

Use revocable for something you can generally cancel or change, and irrevocable for something you generally cannot cancel or change in the same way.

Examples:

• Revocable trust
• Irrevocable trust

These are common terms in US estate planning.

United Kingdom

Use the same spellings and meanings.

Canada

Australia

Australian English also uses both words.

For legal or financial writing, check the relevant Australian terminology and legal requirements.

International writing

For an international audience, explain the word briefly if the context is technical.

For example:

This makes the meaning clear to readers who may not know legal vocabulary.

Academic writing

Use revocable and irrevocable precisely.

Business writing

Use these words when discussing permissions, contracts, authority, or financial arrangements.
