The at sign, @, normally read aloud as "at", also commonly called the atsymbol or commercial at, and less commonly a wide range of otherterms,[1][2][3][4] is originally an accounting and commercial invoiceabbreviation meaning "at the rate of" (e.g. 7 widgets @ 2 = 14). In recentyears, its meaning has grown to include the sense of being "located at" or"directed at", especially in email addresses and social media, particularly

Twitter.It was not included on the keyboard of the earliest commercially successfultypewriters, but was on at least one 1889 model[5] and the very successfulUnderwood models from the "Underwood No. 5" in 1900 onward. It is nowuniversally included on computer keyboards. The mark is encoded atU+0040 @ COMMERCIAL AT (HTML: @ ).[Note: The following information implies that there is a need to go outsidethe English language to nd a single-word name for the "at sign." However,this is not necessary, since the term "at sign" began to be used in 1982 forthe symbol "@."[6]] The fact that there is no single word in English for thesymbol has prompted some writers to use the French arobase[7] or Spanishand Portuguese arrobaor to coin new words such as asperand,[3]ampersat[8] or apetail[citation needed]but none of these has achieved wideusage.
