A selfie (ˈsɛlfi) is a self-portrait photograph, typically taken with a digital camera or smartphone, which may be held in the hand or supported by a selfie stick. Selfies are often shared on social media, via social networking services such as Facebook, Instagram, Threads, Twitter, and Snapchat.
They are often casual in nature (or made to appear casual). A "Selfie" typically refers to self-portrait photos that are taken with the camera held at arm's length, as opposed to those taken by using a self-timer or remote. A selfie, however, may include multiple subjects however; as long as the photo is being taken by one of the subjects featured, it is considered a selfie. However, some other terms for selfies with multiple people include usie, groufie, and wefie. Alternatively, one can take a mirror selfie, with the camera pointed at a mirror instead of directly at one's face, often to get a full-body shot.
"Selfie" is an example of hypocorism – a type of word formation that is popular in Australia where it was in general use before gaining wider acceptance.
The first known use of the word selfie in any paper or electronic medium appeared in an Australian internet forum on 13 September 2002 – Karl Kruszelnicki's 'Dr Karl Self-Serve Science Forum' – in a post by Nathan Hope. Although Hope later dismissed the notion that he coined the term, describing it as "something that was just common slang at the time, used to describe a picture of yourself", he wrote the following: "Um, drunk at a mates 21st, I tripped ofer [sic] and landed lip first (with front teeth coming a very close second) on a set of steps. I had a hole about 1cm long right through my bottom lip. And sorry about the focus, it was a selfie."
By 2013, the word "selfie" had become commonplace enough to be monitored for inclusion in the online version of the Oxford English Dictionary, which announced it as the "word of the year" in November and gave it an Australian origin.
In August 2014, "selfie" was officially accepted for use in the word game Scrabble.
