Origin & History of “at”
The preposition at was originally found throughout the Germanic languages: Old English had æt, Old high German az, Gothic and Old Norse at. It survives in the Scandinavian languages (Swedish att, for instance) as well as English, but has been lost from German and Dutch. Cognates in other Indo-European languages, including Latin ad ‘to, at’, suggest an ultimate common source.
