The at-sign, also known as the "at symbol" or the "commercial at," is a familiar symbol on keyboards and electronic devices. However, depending on the context and country, it can be referred to by different names. For example, in the United Kingdom, it is sometimes called the "at-mark," and in Greece and Italy, it is known as the "alpha-omega." Other synonyms for the at-sign include the "ampersat," "arobase," "monkey's tail," "snail," and "spider monkey." While the at-sign's name may vary, its purpose remains the same, functioning as a separator in email addresses and social media user handles.
