In English language, both advisor and adviser are nouns and has the exact same meaning i.e. a person who gives advice or counsel regarding a particular field. Now let’s discuss which advisor to use when and what the actual difference between the two is.
The simple answer to this is that both of these are acceptable forms when writing or speaking English but that’s not all there is to it.

Adviser vs. Advisor


Adviser with an e dates back to 18th century and is preferred over advisor with an o. Writers, dictionaries and usage guides like Garner’s, Fowler’s and AP Stylebook choose adviser whenever implying a person who gives advice. Its older origin is clearly the reason behind its dominance. The Oxford English Corpus demonstrations that adviser with an e occurs three times as often as advisor with an o.

Emily is thinking of visiting an adviser to consult her immigration issues.


Although in British and American English both adviser predominates, but the predominance of adviser is a little less in American English than the rest of the English communities. However, the myth that advisor with an o is preferred in American English is not true at all. It has been professed that advisor is usually employed to refer to most of the job titles in North America like academic advisor or financial advisor. This gives a formal tone to advisor and deter its definition to someone who gives advice for a living.

Mark was appointed the financial advisor to the estate.

Proper nouns or names should however, always be spelled the way they are. For instance, the president’s Council for on Economic “Advisers” should always be spelled like that as this is its official spelling.

Adviser as an Adjective:

As discussed before, adviser (noun form) with an e is the preferred form in all English communities around the world but advisor is always used whenever it is employed to describe a noun. The adjectival form of adviser is always an advisory. This may be the main reason that stirs up confusion between the two.

My company’s adviser resigned.
The person performing the advisory role for my company resigned.

Note that in this example, adviser with an e is used for representing a noun while advisor with an o is used for representing the adjective. Another important point to remember here is that as a noun, adviser or advisor both can be used interchangeably but, as an adjective only advisor(y) is acceptable.

Adviser or advisor:

In a nutshell, adviser and advisor both mean the same thing and both are acceptable in English language. adviser is ancient and a preferred choice while advisor is utilized when referring to official titles. When using it as an adjective, advisor with an o is the only suitable choice and adviser is not accepted in that manner.

    Nobody writes or says "advisery." Hence, advisor is the better choice, just like protestor is better than protester. The -er spellings are for people who just write what they hear and don't know any better.
