AFAIK is a quick disclaimer that lets your reader know that you’re pretty sure about something, but not completely certain. AFAIK stands for "As Far As I Know." It tells the reader that you are correct — to the best of your knowledge.
AFAIK as an Abbreviation
AFAIK is a popular texting and message board initialism. Both uppercase AFAIK and lowercase afaik are pronounced using the letters, not as a whole word. AFAIK is usually typed, so you’re not likely to hear AFAIK pronounced in spoken conversation at all.
History of AFAIK
Like many abbreviations used online, AFAIK likely dates back to the early days of SMS (Short Message Service) and IRC (Internet Relay Chat) in the 1990s. Messages on these services had very short character limits, so users had to abbreviate phrases to make them fit. As communication technology became more advanced, these character limits weren’t necessary. However, terms such as AFAIK, LOL and BRB are still common internet slang.
Usage of AFAIK
People use AFAIK when they’re not 100% sure about the answer. Synonyms for AFAIK may include:
I think
to the best of my knowledge
but don’t take my word for it
double-check to be sure
don’t quote me on this
yes, probably
Examples of AFAIK
You can use AFAIK at the beginning of a sentence, the end of a sentence or alone as an answer to a question. For example:
AFAIK, the party is still happening tomorrow night.
That computer is on sale down the street AFAIK.
AFAIK Kyra and Cody are still going out.
The movie theater will be open for another week, AFAIK.
AFAIK James has never been out of the country.
AFAIK is also another way to say “as far as I’m concerned” or “in my experience.” These are opinion statements from the writer’s perspective. For example:
AFAIK, La Taqueria is the best Mexican restaurant in town.
Mrs. Harper is a good teacher AFAIK.
AFAIK my brother has the best jump shot on the basketball team.
The nicest casino in Las Vegas is Excalibur, AFAIK.
AFAIK, it’s not safe to drive in the rain.
