Advisor or Adviser? Both Are Correct, and One Is Older
An advisor is someone whose job is to give advice. The spelling adviser is older and still preferred by many editors, but both are standard English.
An advisor gives advice professionally: a financial advisor, a legal advisor, an academic advisor. The role implies expertise and, usually, a formal relationship.
The two spellings cause endless argument. Adviser is the older English form; advisor arrived later under Latin influence. Both are correct; the -or spelling is more common in the United States and in job titles.
- A professional who gives advice. *Speak to a financial advisor.*
- An academic mentor. *Her thesis advisor approved the topic.*
- A political counsellor. *The president's national security advisor.*
