During the coronavirus pandemic, German public health advice was condensed into three letters, AHA: Abstand, Hygiene, Alltagsmaske, distance, hygiene, everyday mask. Indoors an L was added, for Lüften, airing the room. After the meeting of the chancellor and the state premiers in October 2020, the federal government’s website showed the AHA+A+L-Formel. The second A stood for the Corona warning app. The Society for the German Language placed AHA fifth among its Words of the Year 2020.
