'Adviser' vs 'Advisor' : What’s the Difference?

By Carly Forsaith, updated on February 3, 2023

You might have seen these two different spellings for the same word being used and wondered: is it 'adviser' vs 'advisor'? After reading this article, you'll no longer wonder.

The reality is these two spellings are both correct and, therefore, 'adviser' and 'advisor' are interchangeable.

The Difference Between 'Adviser' vs 'Advisor'

'Adviser' vs 'advisor' are, in fact, the same word; it just has two possible spellings. Is one of them preferred? Not really. Sure, if you search online, you'll find different sources crediting a different word as favorite, but the reality is, they're both very commonly used.

The trick, therefore, is to pick one and stay consistent with it. The one thing you don't want to do is switch from one to the other throughout your text. This shows indecision and poor writing skills.

For the purposes of this article, I'm going to pick 'adviser.'

What's an 'Adviser?'

Okay, so we've clarified the spelling, but what does the word actually mean? If a teacher is someone who teaches, a trainer is someone who trains, and an actor is someone who acts, then an adviser is someone who advises.

To advise someone is to give them your opinion or expert thoughts on what they should do.

'Adviser' is a noun, and 'to advise' is its verb.

The word comes from the Latin videre meaning "to see".
