title: At sign text: the "Underwood No. 5" in 1900 onward. It started to be used in email addresses in the 1970s, and is now universally included on computer keyboards. The fact that there is no single word in English for the symbol has prompted some writers to use the French arobase or Spanish and Portuguese arroba, or to coin new words such as the "highly logical" ampersat, asperand, and the strudel, but none of these has achieved wide use. In unicode, the at sign is encoded as , or codice_1 in HTML5.
