@

Commonly referred to as the 'at' symbol, this enigmatic little mark has no official name. However, many countries and their languages attempt to describe it:

apenstaartje - Dutch for "monkey's tail"
snabel - Danish for "elephant's trunk" 
kissanhnta - Finnish for "cat's tail" 
klammeraffe - German for "hanging monkey" 
papaki - Greek for "little duck" 
kukac - Hungarian for "worm" 
dalphaengi - Korean for "snail" 
grisehale - Norwegian for "pig's tail" 
sobachka - Russian for "little dog"

While the exact origin of the @ symbol is not known, many believe it to be from the Medieval Ages and was used for shorthand as the printers tried to be more efficient. The irony there is that we are now using it in ways not too dissimilar from their motivations. We use it in our email addresses, our twitter names and now as the prompt for tagging people in facebook statuses. 

The @ symbol is finally getting its due after hundreds of years. From the printing presses of the monks to the shiny macs of the twitterati.
